Abstract:
Frontier nanophysics in conjunction with nanomedicines, nanoscience and nanotechnology (NNN) developed before the science of analytical chemistry has been very challenges with many competitive obstacles to improve the accuracy and precise nm measurements in order to find out the point of its main chemical structure compositions, uniformity and the concentration contents to each substance. Moreover, exotics nanomaterials either in pure organic and inorganic compound or in hybrid organic-inorganics nanomaterials have shown their remarkable as well as attractive impacts in many nanotechnology and related industrial applications such as in ultrafast picosecond or femtosecond telecommunication integrated circuits and devices system, cosmetics and beauty products, as well as health or pharmaceutical drugs and herbal medicines. In this short communication paper, one explains how to educate first those who are eager indeed to study and expand their knowledge in the discovery level of understanding the nature of chemistry materials. Such guide will involve at least two to three parts of knowledge and skills consisted of the origin of life, electronics of molecular system (MES), and precise or accurate measurements. By implementing these advices, one believes the progress of applied physics frontier works in analytical chemistry will soon obtain a good harvest in the near future.

Abstract:
Although various synthetic methodologies including organic synthesis, polymer chemistry, and materials science are the main contributors to the production of functional materials, the importance of regulation of nanoscale structures for better performance has become clear with recent science and technology developments. Therefore, a new research paradigm to produce functional material systems from nanoscale units has to be created as an advancement of nanoscale science. This task is assigned to an emerging concept, nanoarchitectonics, which aims to produce functional materials and functional structures from nanoscale unit components. This can be done through combining nanotechnology with the other research fields such as organic chemistry, supramolecular chemistry, materials science, and bio-related science. In this review article, the basic-level of nanoarchitectonics is first presented with atom/molecular-level structure formations and conversions from molecular units to functional materials. Then, two typical application-oriented nanoarchitectonics efforts in energy-oriented applications and bio-related applications are discussed. Finally, future directions of the molecular and materials nanoarchitectonics concepts for advancement of functional nanomaterials are briefly discussed.

Abstract:
Progress of modern analytical chemistry is closely related with advancement in other fields such as organic chemistry and biochemistry. Successful solution of current scientific problems is inconceivable without close cooperation of different chemical disciplines. As an example of such hot and very intricate theme research in the field of molecular recognition of biologically active compounds can serve, where numerous methods of analytical chemistry, organic chemistry and biochemistry can suitably be utilized, elaborated and brought into consonance. This multidisciplinary overlap logically leads to the advent of new scientific fields with their own tools, methodologies and subjects of exploration - bioanalytical chemistry and nanotechnology. This review covers different aspects of analytical application of oligopyrrole macrocycles (mainly porphyrins and sapphyrins). These compounds are widely used in analytical chemistry due to their outstanding optical properties. In our contribution oligopyrrole macrocycles are considered as signaling and structural parts of chemical receptors and selectors in various applications. Introduction of different moieties into meso-position of macrocyclic rings allows to obtain e.g., sterically well-organized receptors for recognition of biologically important analytes, new chromatographic materials, and powerful tools in electrochemical research. Finally, future trends in the field are outlined briefly.

Abstract:

Organic chemistry used to augment nanoparticles and nanotubes, as well as more traditional materials, is a subject of great interest across multiple fields of applied chemistry. Herein we present an example of both nanoparticle and nanotube augmentation with organic small molecules to achieve an enhanced or otherwise infeasible application. The first chapter discusses the modification of two different types of Microbial Fuel Cell (MFC) anode brush bristle fibers with positive surface charge increasing moieties to increase quantitative bacterial adhesion to these bristle fibers, and therefore overall MFC electrogenicity. Type-1 brush bristles, comprised of polyacrylonitrile, were modified via the electrostatic attachment of 1-pyrenemethylamine hydrochloride. Type-2 brush bristles, comprised of nylon, were modified via the covalent attachment of ethylenediamine. Both modified brush types were immersed in an E. Coli broth for 1 hour, stained with SYTO® 9 Green Fluorescent Nucleic Acid Stain from ThermoFisher Scientific (SYTO-9), and examined under a Biotek Citation 3 fluorescent microscope to visually assess differences in bacterial adherence. In both trials, a clear increase in amount of bacterial adhesion to the modified bristles was observed over that of the control. The second chapter demonstrates a potential biomedical technology application wherein a polymerizable carbocyanine-type dye was synthesized and bound to a chitosan backbone to produce a water-soluble photothermal nanoparticle. Laser stimulation of both free and NP-conjugated aqueous solutions of the carbocyanine dye with Near-Infrared (NIR) Spectrum Radiation showed an increase in temperature directly correlated with the concentration of the dye which was more pronounced in the free particle solutions.

Abstract:
Owing to the importance of gold nanoparticles in catalysis, designing of them has become a major focus of the researchers. Most of the current methods available for the synthesis of gold nanoaprticles (GNPs) suffer from the challenges of polydispersity, stability and use of toxic and harmful chemicals. To overcome these limitations of conventional methods, in our present study, we made an attempt to design a method for the green synthesis of monodispersed and stable gold nanoparticles by sugars which act as reducing and stabilizing agent. Characterization of synthesized nanoparticles was done by using various analytical techniques such as transmission electron microscope (TEM), dynamic light scattering spectroscopy (DLS), UV-Vis spectroscopy, scanning electron microscopy and electron dispersion spectroscopy. The synthesized sugar GNPs (S-GNPs) were spherical in shape and in the size range of 10 ± 5 nm. p-Nitrophenol reduction assay was used as a model system to determine the catalytic reduction activity of various sugar capped GNPs, monosaccharides (fructose), disaccharide (sucrose) and trisaccharide (raffinose) GNPs. The effect of temperature and the size of ligand on catalytic activity was also evaluated at different temperature using UV-Vis spectrometer. Using the spectroscopic data, rate constant (k) for three sugar capped GNPs was determined followed by its activation energy (Ea) and exponential (A) factor.

Abstract:
Various synthetic methods have been developed to produce metal nanostructures including copper and iron nanostructures. Modification of nanoparticle surface to enhance their characteristic properties through surface functionalization with organic ligands ranging from small molecules to polymeric materials including organic semiconducting polymers is a key interest in nanoscience. However, most of the synthetic methods developed in the past depend widely on non-aqueous solvents, toxic reducing agents, and high temperature and high-pressure conditions. Therefore, to produce metal nanostructures and their nanocomposites with a simpler and greener method is indeed necessary and desirable for their nano-scale applications. Hence the objective of this thesis work is to develop an environmentally friendly synthesis method to make welldefined copper and iron nanostructures on a large-scale. The size and shape-dependent optical properties, solid-state crystal packing, and morphologies of nanostructures have been evaluated with respect to various experimental parameters. Nanostructures of copper and iron were prepared by developing an aqueous phase chemical reduction method from copper(II) chloride and Fe(III) chloride hexahydrate upon reduction using a mild reducing agent, sodium borohydride, under an inert atmosphere at room temperature. Well-defined copper nanocubes with an average edge length of 100±35 nm and iron nanochains with an average chain length up to 1.70 μm were prepared. The effect of the molar ratios of each precursor to the reducing agent, reaction time, and addition rate of the reducing agent were also evaluated in order to develop an optimized synthesis method for synthesis of these nanostructures. UV-visible spectral traces and X-ray powder diffraction traces were obtained to confirm the successful preparation of both nanostructrues. The synthesis method developed here was further modified to make poly(3-hexylthiophene) coated iron nanocomposites by surface functionalization with poly(3-hexylthiophene) carboxylate anion. Since these nanostructrues and nanocomposites have the ability to disperse in both aqueous-based solvents and organic solvents, the synthesis method provides opportunities to apply these metal nanostructures on a variety of surfaces using solution based fabrication techniques such as spin coating and spray coating methods.

This dissertation presents the development of a synthetic strategy to produce various spiroligomer-based macrocycles that bridge the gap between organic molecules and small proteins. “Spiroligomers” (formerly known as “bis-peptides”) are a class of molecules produced by the assembly of “bis-amino acids”, molecules containing two amino acid regions on a single cyclic core. Each bis-amino acid is connected through pairs of amide bonds to form a diketopiperazine consequently eliminating single bond rotation and, therefore, avoids the complicated folding process common to the field of peptidomimetics. Spiroligomers are shape-programmable since the three-dimensional structure is controlled by the stereochemistry of the bis-amino acid monomers used in the synthesis, the connectivity of the monomers, and the number of monomers used. Furthermore, bis-amino acids can contain additional functional groups attached to multiple locations on the monomer which allows each spiroligomer, once synthesized, the ability to display these functional groups in predictable three-dimensional coordinates, with respect to each other. The synthesis of large spiroligomer-based structures requires the production of large amounts of bis-amino acid monomers. To this end, the scale of the synthesis of proline-based bis-amino acids from inexpensive trans-4-hydroxy-L-proline has been increased roughly 5-fold with respect to the previously published method. In addition to the time and solvent savings as a result of increasing the scale, the synthetic steps have been altered with considerations to ensure the production takes place in a convenient and environmentally friendly manner. Additionally, the desire to synthesize large spiroligomer-based structures means that the synthesis of each spiroligomer fragment must be as efficient and high-yielding as possible. To achieve this goal, a new synthetic approach to highly functionalized spiroligomers on solid support has been developed that results in increased yields relative to previously published methods. This new approach makes use of a protecting group, para-nitrobenzyl carbamate, which has not previously been incorporated in bis-amino acids as well as a pentafluorophenol ester activation strategy that also has not been in the synthesis of spiroligomers. Finally, an extendable synthetic route to spiroligomer-based macrocycles has been developed and representative macrocycles have been synthesized. This approach uses solid support to assemble multiple spiroligomers together through amino acids linkers before being cyclized in solution at dilute concentration to yield the desired macrocycles. Minimal functionality was included in the representative macrocycles to simplify structural information, confirmed by NMR and other means, and the macrocyclic structures were further investigated for host-guest activity using fluorescent, solvatochromic dyes.

Abstract:
Synthetic polymeric materials have gained significant use as biological materials (biomaterials) in biomedical and pharmaceutical applications. As a result, a demand for well-defined polymers with tunable properties has emerged. The synthetic versatility of polymeric biomaterials allows the opportunity to understand the structure-property relationship of materials and their cellular interactions. A novel class of polymeric biomaterials are conjugated polymers (CPs), which possess desirable physicochemical and excellent photophysical properties, including inherent fluorescence. The synthetic versatility of CPs allows easy modification of the conjugated backbone to tune emission and side chain structures to adjust biocompatibility through increased water solubility, controlled biodegradability, and incorporation of targeting units. The aim of this dissertation is to better understand conjugated polymer nanoparticle (CPN) structure and self-assembly in an aqueous environment, and how those structural features affect cellular interactions to establish a structure-function relationship. This work presents the fabrication of several different CPNs for cancer cell targeting and labelling, and differentiation of biologically important molecules. Core−shell nanoparticles were prepared using a semi-flexible cationic CPN complexed with hyaluronic acid (HA), a polyanion. The resulting CPNs exhibited high cancer cell specificity with low adsorption to normal cells, as a result of HA’s affinity towards overexpressed receptors on cancer cell surface. A systematic investigation on the aggregation properties of CPNs that vary by side chain and backbone structures in response to different biologically important anionic polysaccharides in a complex biological medium was conducted. Mitochondria-specific CPNs were fabricated from a semi-flexible CPN modified with the mitochondrial-targeting triphenylphosphonium (TPP) group. The subcellular localization and cellular toxicity were dependent on backbone flexibility, hydrophilicity, and molecular weight. Dual-targeting CPNs grafted with folic acid (FA) side chains and complexed with hyaluronic acid (HA) were fabricated for improved uptake and bioimaging of cancer cells. The work presented here shows how modifications to CPN backbone and side chain structures modulate their cellular interactions. The physicochemical and biophysical properties of CPNs affect biocompatibility and understanding those properties will lead to the development of novel CP-based biomaterials.

Nanotechnology offers multiple benefits. Nanomedicine and nanodelivery systems are relatively new areas in nanotechnology. There are number of outstanding applications of the nanomedicine in diagnosing diseases, delivering drugs to its target location, and thus treating human diseases. Here materials in the nanoscale range are employed to serve as means of diagnostic tools and also to deliver precise medicines to specific targeted sites in a controlled manner. Also, metal nanoparticles offer great interest in modern chemistry and materials research because of their applications in diverse fields such as photochemistry, nanoelectronics, optics, and catalysis. Chemistry provides various nanostructured materials either synthetic or isolated from natural sources offers opportunities and challenges in drug delivery and their applications including biomedical imaging, biosensing, diagnostic, and therapy. Thymoquinone, a bioactive compound in Nigella sativa, after encapsulation in lipid nanocarrier, has been found to show six-fold increase in bioavailability in comparison to free thymoquinone. In addition to this, organic nanomaterials have recently become of great interest for photovoltaic applications also.

Abstract:
There are many challenging intellectual opportunities for the research community to create new knowledge in molecular structure–property relations, and to enlarge the toolbox of product engineering, that promise to inspire and accelerate new product innovations. There is a suspicion that there are inexhaustible families of material structures waiting to be discovered and to be used. Periodically, this suspicion is confirmed by the announcement of yet another family of interesting materials. In the 1970s, the synthetic zeolites were heralded as a new class of compounds with a microstructure of pores with molecular sizes. These became very useful in making adsorbents and catalysts. This discovery also led to the invention of many other families of microporous materials. Then came the broader concept of self-assembly of material, namely of organic and inorganic compounds that organize themselves into intricate patterns, now counted within the umbrella of nanotechnology. Two of the recent Nobel Prizes in chemistry offer proof that this field of new synthesis is full of possibilities and honor. We once thought that carbon existed only in the graphite, diamond, and amorphous forms. Now we know that not only can it exist in the buckminsterfullerene form of C60, but also in many other related forms that are spherical and cylindrical tubules. The notion of an electrically conducting polymer was not seriously considered until the invention of the electrically conducting polyacetylenes by Heeger, McDiarmid, and Shirakawa. The synthesis of new material can also be divided into the twin paths of incremental synthesis of the derivatives of known structures and the wildcat synthesis of totally unrelated structures. The incremental approach is used when a material with interesting properties is discovered, and research chemists will swarm around it to make every conceivable derivative to see whether they can enlarge the menu to choose from, and to ensure that the new province is well explored. The opposite wildcat approach seeks new and exciting families of material that would not be found by adhering exclusively to known provinces. The discovery of interesting natural materials not recognized before is a continuing theme of romance.

Uninterrupted supply of adequate and clean drinking water is a fundamental human necessity, and essential to maintain the healthy surroundings. It also influences the development and economic growth, specifically in developing countries. It provides an excellent opportunity for treatment of surface water, groundwater, and wastewater contaminated by toxic metal ions, organic and inorganic solutes, and microorganisms. It facilitates an opportunity to optimize the current conventional techniques and to offer novel and innovative methods of water purification. Various nanomaterials on which purification of contaminated drinking water is based includes nanostructured catalytic membranes, nanosorbents, nanocatalysts, and bioactive nanoparticles. Current and potential applications of nanotechnology in water purification are adsorption, membrane separation processes, photocatalysis, disinfection, and microbial control. This chapter reviews the recent research efforts accomplished in the area of nanotechnology for drinking water purification.

Abstract:
This chapter shows the experimental findings on preparing TiO2 nanotubes by anodizing titanium into an organic medium for an intended use as a fotocatalytic active electrode in treating water polluted with organic contaminants. The substrates were grit blasted in order to obtain mechanical fixation of the generated nanotubular TiO2 structure. This was successfully achieved without diminishment of the nanotubes order and with a self-leveled outer surface. A new phenomenon occurred when detached fragments from the modified layer were electrophoretically deposited. They were ordered and grow as deposits. In addition, they maintain their nanotubular shape conferring a homogeneous size in the porous structure.

Abstract:
This chapter shows results related to synthesizing hybrid materials composed of polymer matrix/nano-TiO2, which possesses a photochromic property under UV irradiation. The synthesized TiO2 was amorphous, but, for the hybrid photochromic response, the required illumination is that with the same or superior energy than semiconductor bandgap. Moreover, the photochromism requires OH proportionate to preparing within an alcohol, and by releasing them by temperature, the color change resulted permanent. The hybrid materials were prepared as coatings, which display multifunctional characteristics. The polymeric matrix was proven with different kinds of organic polymers and solvents. This phenomenon was investigated through Salt Spray Test, Electrochemical Impedance Spectroscopy, HRTEM, SEM, Reflectance, Fluorescence, Contact Angle, and EPR. The capacity to act as a barrier for corrosion protection was investigated. Finally, the hybrid material is proposed as an indicator for applications in engineering.

Abstract:
Nanotechnology is a rapidly growing research fields with many applications in biology and medicine. At a heart of nanotechnology research is engineered nanostructures, which possess distinct optical, electronic, and magnetic properties based on their size, shape, and chemical composition. Researchers can now design their surface chemistry with small bi-functional organic molecules or amphiphillic polymers so that they are biocompatible and can be coated with bio-recognition molecules such as antibodies, aptamers, and peptides. Nanoparticles are used as a platform for drug delivery, as a physical trigger for controlling drug release, as a contrast agent for quantifying biological molecules. Thus, the applications of engineered nanostructures are diverse. In this presentation, an overview of the field of nanomedicine is described with an emphasis on results obtained from studying the in vivo interactions of nanostructures as it pertains to their applications in cancer.
