Abstract:

<p>The aims of this study are to first immobilize positively charged gold nanorods to negatively charged cell culture surfaces. Second, to use polyelectrolytes for controlling the distance between gold nanorods and fluorophores. This is used to optimally determine the distance, of which maximum fluorescence enhancement is achieved, between gold nanorods and fluorophores. In order to approach these aims, we use UV/VIS absorption spectroscopy, fluorescence spectroscopy, atomic force microscopy, and ellipsometry. The results show that we could control the immobilization of gold nanorods on plasti

Abstract:

Gold nanorods (GNRs) with a high dimensional ratio were obtained by seed mediated synthesis. In order to obtain the lowest ratio of shape impurities, 5 bromosalicylic acid was used as additive; a controlled dissolution of the additive resulted to be necessary for obtaining a low ratio of shape impurities. The effect of silver concentration in the growth solution was also investigated, showing its influence related to a change in the size ratio of the obtained GNRs. Furthermore, XRD analysis showed that silver precipitation occurs above a specific Ag concentration. The synthesis reproducibili

In recent years, several groups have investigated the changes of chemical and physical properties of materials with size in the nanometer scale. These studies have highlighted a number of possible applications for nanostructures, which are now employed, for example, in biology and medicine for imaging, disease detection, diagnosis, sensing and therapy. In noble metals, the coherent collective oscillation of electrons in the conduction band (Surface Plasmon Resonance, SPR), induces large surface electric fields which greatly enhance the radiative properties of gold and silver NPs when they int

Abstract:

A novel localized surface plasmon resonance (LSPR) sensor that differentiates between background refractive index changes and surface-binding of a target analyte (e.g. a target molecule, protein, or bacterium) is presented. Standard, single channel LSPR sensors cannot differentiate these two effects as their design allows only one mode to be coupled. This novel technique uses two surface plasmon modes to simultaneously measure surface binding and solution refractive index changes. This increases the sensitivity of the sensor. Different channels or modes can be created in sensors with the intro

Abstract:

A series of Pt-coated gold nanorod (Au NR) electrocatalysts were prepared. STEM images showed that Pt nanodots grew epitaxially on the Au NR surface. A CO blocking technique was used in order to coat Pt in a more controlled, uniform manner. The nanorods were characterised using UV-visible spectroscopy and, after being immobilised onto a supported glassy carbon electrode, with cyclic voltammetry. The CO blocking technique was crucial in enhancing CO electrooxidation and oxygen reduction reaction activity of the nanorods, not only because of the higher coverage of Pt nanodots but also because of

The increase in the magnitude of local electric fields through resonances of plasmonic excitations in metallic nanoparticles is a major area of current optical research.

By matching the plasmon resonance of the gold nanorods to the wavelength of the fundamental light, it is possible to greatly enhance the SHG efficiency.

Abstract:

碩士<br>國立臺灣大學<br>應用力學研究所<br>99<br>In this thesis, we studied the interactions among fluorescent molecules, visible light and gold nanorods (GNRs) or silica-coated gold nanorods, nonconcentric gold nanoshell (GNSs). Based on Maxwell''s equations, the multiple-multipole (MMP) method was used to solve these problems. We studied the surface plasmon resonances (SPRs) of these nanoparticles irradiated by different incident plane waves with different polarizations. In additionally, the average effect was studied by considering all possible incident directions. Moreover, the electric dipole w

博士<br>國立中正大學<br>化學暨生物化學研究所<br>101<br>There are two biosensing approaches based on surface enhanced Raman spectroscopy (SERS): surface enhanced Raman tags (SERS tags) and label-free methods. In this study, the biosensor fabrication methodology and the signal amplification technique can be described as the following three parts: First, the status of protective layer of cetyltrimethylammonium bromide (CTAB) on gold nanorod (AuNR) surface can be modulated by controlling the concentration of CTAB. Thus, the monodispersive SERS core-shell tag based on an AuNR was fabricated successfully. Because of

碩士<br>國立成功大學<br>化學系<br>103<br>Lanthanide-doped upconversion nanoparticles converting near-infrared light to visible light have been recognized as an efficient and versatile tool of bioimaging and cancer therapy. Herein, we synthesize upconversion nanorods coated with silica shell modifying (3-Aminopropyl)triethoxysilane outside the surface. And these UCNP@SiO2-APTES are encapsulated in gold nanoshell by well-known seed growth method. After accomplishing double layer core shell UCNP@SiO2-Au shell, the final step is to etch the silica layer in basic ammonia solution by hydrolysis and construct a

Moreover, cell viability was simultaneously determined through in situ real-time observations of cell morphology and cell membrane permeability. In Coordination with the 670 nm~880 nm near infra-red (NIR) penetration window of human tissue, Au-NR with aspect ratios of 3.92 were strictly synthesized through water based chemical methods. Such produced aspect ratio correspo
