Water soluble metallic nanoparticles are being developed for a variety of roles ranging from catalysis to drug delivery and as potential contrast agents. We demonstrate direct synthesis of high-quality water-soluble Au, Ag, Pt, Pd, Cu and alloyed AuPt nanoparticles as well as ligand-exchange of FePt, cubic Pt and Au/Pt core/shell nanoparticles using bidentate dithiolane PEG as a universal ligand. Simple chemistry can greatly expand the applications of metal nanoparticles.
水溶性金属纳米颗粒正被开发用于从催化到药物递送等各种用途，并作为潜在的造影剂。我们展示了使用双齿二硫杂环戊烷聚乙二醇作为通用配体直接合成高质量的水溶性金、银、铂、钯、铜和合金化金铂纳米颗粒，以及对铁铂、立方铂和金/铂核壳纳米颗粒进行配体交换。简单的化学方法可以极大地扩展金属纳米颗粒的应用。
