General description
Goldis a highly valued metal in catalysis and material science due to its uniqueproperties such as high chemical stability, excellent electrical and thermalconductivity, malleability, and ductility. In catalysis, gold nanoparticles areparticularly effective as catalysts for various chemical reactions, includingoxidation and hydrogenation processes due to their high surface area andexcellent catalytic activity. In material science, gold is often employed inthe fabrication of electronic components, sensors, and biomedical devices dueto its excellent conductivity, corrosion resistance, and biocompatibility.
Application

Gold nanoparticles (AuNPs) are of biomedical importance, such as delivery vectors. Therefore, we used all-atom molecular dynamic simulations to study the interaction of AuNPs with cell membrane (DMPC bilayer). We observed that the AuNPs adhered spontaneously on the surface of

Multifunctional phosphine based ligands, 1,1,1-tris(diphenylphosphinomethyl)ethane [CH3C(CH2 PPh2)3][P3] and 1,1,1-tris(diphenylphosphinomethyl)ethane trisulphide [CH3C(CH2P(S)Ph2)3][P3S3] have been introduced to stabilize Au(o)-nanoparticles having small core diameter and narrow size distribution. The Au(o)-nanoparticles were synthesized by the reduction of HAuCl4 precursor with NaBH4 in the presence

We report on the enhancement of sensitivity of SPR biosensor by modifying the metal surface. A mixture layer, in which gold and dielectric medium coexist, was simply prepared by increasing the roughness of gold surface deposited onto a glass substrate
