Colloidal gold and silver triangular nanoprisms.
It is now well-known that the size, shape, and composition of nanomaterials can dramatically affect their physical and chemical properties, and that technologies based on nanoscale materials have the potential to revolutionize fields ranging from catalysis to medicine. Among these materials, anisotropic particles are particularly interesting because the decreased symmetry of such particles ofte...
متن کاملEffect of colloidal silver nanoparticles and silver nitrate on hematological indices of Zayandehrud Chub (Petroleuciscus esfahani)
Effects of different concentrations of silver nanoparticles and silver nitrate on some hematological indices of Zayanderud Chub (Petroleuciscus esfahani) were investigated. One hundred individuals of the fish (average weight 26.4 ± 1.3 g) were divided into 5 experimental groups, exposed to 1 or 25 µg/L of silver nano or silver nitrate or unpolluted water as control for 10 days. At the end, prim...

متن کاملInteraction of Colloidal Silver Nanoparticles with Ni2+: Sensing Application
We report on synthesis of silver nanoparticles (AgNPs) capped with specific thiol suitable to detect heavy metal ions in water. The sensing mechanism is based on a change of an optical properties of the silver colloids, namely the surface plasmon resonance (SPR) when small amounts of contaminants are present in solution. We detected a specific sensitivity to nickel ions and we investigated the ...
متن کاملFeasibility of colloidal silver SERS for rapid bacterial screening
This study reports the feasibility of citratereduced colloidal silver surface-enhanced Raman scattering (SERS) for differentiating three important food borne pathogens, E. coli, Listeria, and Salmonella. FT-Raman and SERS spectra of both silver colloids and colloidK3PO4 mixtures were collected and analyzed to evaluate the reproducibility and stability of silver colloids fabricated in a batch-pr...
