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.
金属纳米粒子由于其在电子学、光电学、生物科学、催化等领域的潜在应用而引起了极大的关注。新的配体 1,1,1-三（二苯膦甲基）乙烷 [CH3C(CH2PPh2)3] 1 和 1,1,1-三（二苯膦甲基）乙烷三硫化物 [CH3C(CH2P(S)Ph2)3] 2 被制备用于稳定具有小核心直径的金（°）纳米粒子。金（°）纳米粒子对革兰氏阳性菌（例如金黄色葡萄球菌）比革兰氏阴性菌更具活性。在这两种金（°）纳米粒子中，配体 1 稳定的颗粒显示出更高的活性。
