Abstract:

This thesis examines and exploits the optical properties of pairs of MNPs. Pairs of MNPs offer two further parameters not existent at single MNPs, which both affect the local optical fields in their vicinity: the distance between them, and their relative orientation with respect to the polarisation of the excitation light. These properties are subject of three chapters: One section examines the distance-dependent and orientation-sensitive scattering cross section (SCS) of two equally sized MNPs. Both near- and far-field interactions affect the spectral position and spectral width of the SCS. F

Abstract:

The optical properties of gold in the visible are dominated by the response of the free conduction electrons to light. In gold nanostructures, the surface charge density adopts a configuration that is constrained by the shape of the nanoparticles. As a result, the scattering of light by gold nanoparticles exhibits a resonant response characterised by a strong scattering and absorption in a narrow range of frequencies. The spectral range of this \emph{localised surface plasmon resonance} (LSPR) can be tuned by varying the size and shape of the gold nanoparticle --- the nanoparticles act as nano

Abstract:

Gold nanoparticle has emerged as an attractive platform for drug delivery applications by complementing the existing drug delivery carriers. Currently, only a few gold nanoparticle-based anticancer drug delivery systems have been reported, compared to the polymer-based delivery systems. Additionally, there is still a lack of understanding for the behavior and fate of the gold-drug conjugate in the body that further attention is required. The overall goal of this thesis is to investigate the in vivo behavior of colloidal gold nanoparticle and its therapeutic efficacy in an animal model, especia

Poly(3,4-ethylenedioxythiophene), PEDOT, belongs to the group of conducting polymers and is characterized by its high stability, a moderate band gap and its optical transparency in the conductive state. A large disadvantage of conducting polymers, and also PEDOT, is their poor solubility. One way to achieve processible materials is the synthesis of colloidal particles. Thus, this work focuses on the development of conductive particles by preparing composite structures. Polymeric colloids like latex particles and microgels were used as templates for the oxidative polymerization of EDOT. Dependi

The trapping of microparticles by optical methods using a focussed laser beam, known as optical tweezers, has evolved rapidly in the last thirty years. However this process is limited to the trapping of a small number of particles.

A channel waveguide used to produce such an evanescent wave can be photolithographically defined on a flat substrate and thus can be integrated with other micron scale processes.

Abstract:

Self-assembled microsphere monolayers (SMMs) hold significant promise for micro- and nanopatterning. Here we exploit, for the first time, SMMs as stamps for microcontact printing (μCP) and demonstrate this to fabricate patterned initiator templates that can subsequently be amplified into polymer brushes by surface initiated atom transfer radical polymerization (SI-ATRP). SMM stamps avoid the need for expensive and sophisticated instrumentation in pattern generation, and provide a broad range of accessible surface chemistries and pitch size control.

Abstract:

Colloid displacement lithography is proving to be very effective in the designing of nanometer scale electronic devices. Precise control of the structure of matter at the nanometer scale has brought a revolutionary change in science and technology. The use of these nanometer scale devices ranges from the diagnosis of various diseases to cell repair to ultra strong materials. This research focused on optimizing the conditions for gold colloid particle adsorption for colloid displacement lithography, an expansion on gold colloid particle manipulation techniques using a scanned probe microscope.

Abstract:

碩士<br>國立清華大學<br>材料科學工程學系<br>104<br>Organic light emitting diode (OLED) can be applied to high quality displays and solid-state lightings due to its self-luminous, low-power consumption, wide-viewing angle, lightness, thinness and flexibility. However, to make products more energy-efficient and with longer lifetime, high efficiency OLED research and development are critical. Besides developing new materials or changing device structures, modification can also be achieved by using additive elements. In this study, we incorporated gold nanoparticles into OLEDs, which notably improved the efficacy

Abstract:

碩士<br>國立中正大學<br>物理所<br>97<br>A fiber biosensor modified by nano-gold particles is made according to the localized surface plasma resonance theorem. The nano-gold particles enhances the sensitivity of the sensor measuring the refractive index (RI) by absorbing and scattering the evanescent wave on the interface between the core and the liquid to be tested. Different research teams have used different approaches to achieve the same goal. In this study, we pursue our goal by modification of the fiber with nano-gold particles. This fiber is either tapered or non-tapered in advance. Note that tap

碩士<br>中原大學<br>化學研究所<br>93<br>Abstract This thesis is mainly focused on the preparation and property studies of nanocomposite materials, which containing the dispersed phase of nano-scale gold particles and polyimide (PI) matrix. First of all, the nano-scale gold particles were generated through processing the reduction reactions of HAuCl4 compound by citrate. Subsequently, suitable amount of as-prepared gold nanoparticles were homogeneously added into the poly(amic acid) solution through the direct solution dispersion technique, followed by casting the as-mixing solutions on inorganic glass
