Photovoltage mechanism for room light conversion of citrate stabilized silver nanocrystal seeds to large nanoprisms.

We investigate the photoconversion of aqueous 8 nm Ag nanocrystal seeds into 70 nm single crystal plate nanoprisms. The process relies on the excitation of Ag surface plasmons. The process requires dioxygen, and the transformation rate is first-order in seed concentration. Although citrate is necessary for the conversion, and is consumed, the transformation rate is independent of citrate concen...

Citrate Stabilized Silver Nanoparticles: Study of Crystallography and Surface Properties

Citrate stabilized silver (Ag) colloidal solution were synthesized and characterized for crystallographic and surface properties by using transmission electron microscopy (TEM) and zeta potential measurement techniques. TEM investigation depicted the size of Ago ranges from 5 to 50 nm with smaller particles having single crystal structure while larger particles with structural defects (such as ...

Colloidal synthesis of germanium nanocrystals

In this study, colloidal germanium nanocrystals were synthesized by a simple and novel method, and their optical properties were also studied. Polyvinyl alcohol (PVA) as a surface modifier was used to control the optical properties of colloidal Ge nanocrystals. Fourier transform infrared spectroscopy (FTIR) analysis was performed to identify the various functional groups present in the sample. ...

Citrate-Stabilized Gold Nanorods

Stable aqueous dispersions of citrate-stabilized gold nanorods (cit-GNRs) have been prepared in scalable fashion by surfactant exchange from cetyltrimethylammonium bromide (CTAB)-stabilized GNRs, using polystyrenesulfonate (PSS) as a detergent. The surfactant exchange process was monitored by infrared spectroscopy, surface-enhanced Raman scattering (SERS), and X-ray photoelectron spectroscopy (...

Biomedical Applications of Colloidal Nanocrystals

Because of the high affinity of the thiol groups to a metal such as gold and zinc, we can conjugate metal nanocrystals with chemical compounds which contain thiol such as cysteine, cyctein contained peptide, and thiol-modified nucleic acids including DNA. Among them, T. Pellegrino et al. investigated Gold-DNA conjugates in detail by a comprehensive gel-electrophoresis study based on 1200 gels. ...
