Chitosan-capped gold nanoparticles for selective and colorimetric sensing of heparin
In this contribution, novel chitosan-stabilized gold nanoparticles (AuNPs) were prepared by mixing chitosan with citrate-reductive AuNPs under appropriate conditions. The as-prepared chitosan-stabilized AuNPs were positively charged and highly stably dispersed in aqueous solution. They exhibited weak resonance light scattering (RLS) intensity and a wine red color. In addition, the chitosan-stab...
متن کاملRoom temperature dielectric and antibacterial behavior of thiosemicarbazide capped low dimension Silver and Gold nanoparticles
Room temperature dielectric and antibacterial behavior of thiosemicarbazide capped low dimension Silver and Gold nanoparticles were studied. The effect of size on the properties, by capping silver (Ag) and gold (Au) nanoparticles by thiosemicarbazide (TSC) was investigated. The nanoparticles were synthesized by chemical reduction method. The structural formation, surface morphology, phase stabi...

متن کاملSynthesis and Ultraviolet Visible Spectroscopy Studies of Chitosan Capped Gold Nanoparticles and Their Reactions with Analytes
Gold nanoparticles (AuNPs) had been synthesized with various molarities and weights of reducing agent, monosodium glutamate (MSG), and stabilizer chitosan, respectively. The significance of chitosan as stabilizer was distinguished through transmission electron microscopy (TEM) images and UV-Vis absorption spectra in which the interparticles distance increases whilst retaining the surface plasmo...
متن کاملEfficient pH Dependent Drug Delivery to Target Cancer Cells by Gold Nanoparticles Capped with Carboxymethyl Chitosan
Doxorubicin (DOX) was immobilized on gold nanoparticles (AuNPs) capped with carboxymethyl chitosan (CMC) for effective delivery to cancer cells. The carboxylic group of carboxymethyl chitosan interacts with the amino group of the doxorubicin (DOX) forming stable, non-covalent interactions on the surface of AuNPs. The carboxylic group ionizes at acidic pH, thereby releasing the drug effectively ...
