title: Au(degrees)-nanoparticles: control size and morphology stabilized by tripodal phosphine based ligands and their antimicrobial activity.
abstract: Metal nanoparticles have attracted great attention due to their potential applications in the fields like electronics, opto-electronics, bioscience, catalysis, etc. New ligands 1,1,1-tris (diphenylphosphinomethyl) ethane [CH3C(CH2PPh2)3] 1 and 1,1,1-tris-(diphenylphosphino methyl) ethane trisulphide [CH3C(CH2P(S)Ph2)3] 2 for stabilization of Au(degrees)-nanoparticles having small core diameter were prepared. The Au(degrees)-nanoparticles are more active against Gram(+) bacteria, e.g., Staphylococcus aureus than Gram(-) bacteria. Among the two Au(degrees)-nanoparticles, the ligand 1 stabilized particles shows higher activity.
