of Presentation Presentation Title: Nanooptic with Plasmons – Noble metal and Semiconductor Nanoparticles for Optical Devices Abstract : We produce size and shape controlled metal, semiconducting and hybrid nanocrystals by wet chemical synthesis, 2 especially in microfluidic continuous flow. Understanding We produce size and shape controlled metal, semiconducting and hybrid nanocrystals by wet ...

Over the last several years, our laboratory has described in detail the favorable effects of fluorophores in close proximity to metallic nanoparticles. Metal nanoparticles comprised of gold, silver, copper, and zinc show enhanced fluorescence intensities and photostabilities for fluorophores positioned within 10 nm of the particles. In this paper we show that, in addition to these metals, chrom...

This review provides a broad look on the recent investigations on the synthesis, characterization and physico-chemical properties of noble metal nanoparticles, mainly gold and silver nanoparticles, stabilized with ligands of different chemical nature. A comprehensive review of the available literature in this field may be far too large and only some selected representative examples will be repo...

The formation of three-dimensional self-assembled monolayers (3-D SAMs) generated by the adsorption of n-octadecyl disulfide onto colloidal gold and silver nanoparticles is described. The functionalized nanoparticles were characterized by solubility, transmission electron microscopy, ultraviolet-visible spectroscopy, 1H nuclear magnetic resonance spectroscopy, surface-enhanced Raman spectroscop...

The nanoparticles of gold and silver in solution state and supported over activated alumina are effective systems for the quantitative removal of chlorpyrifos and malathion, two common pesticides found in surface waters of developing nations, from water. In the solution phase, these pesticides adsorb onto the nanoparticles' surfaces and upon interaction for a long time, the nanoparticles with a...

The fabrication and characterization of template silver nanoshell structures and the encapsulation of gold nanoparticles using biocompatible poly(oxyethylene)-poly(butylene) diblock co-polymer vesicles is described in this work. These vesicles have a narrow diameter size distribution around 200 nm. Silver nanoparticles (Ø = 1-10 nm) functionalized with decanethiol were successfully entrapped in...

Vibrio cholerae is a human pathogen that causes mild to severe diarrheal illnesses and has major public health significance. The aim of this study was to investigate the effects of antimicrobial activity of the gold nanoparticles on Vibrio cholera. Gold and Silver nanoparticles are chemically synthesized. Standard strain of Vibrio cholerawas cultured in a nutrient broth. Minimum inhibitory conc...
