负电荷磷脂DSPG双层保护的金纳米粒子的合成与表征

Synthesis and Characterization of Anionic Phospholipid DSPG Bilayer Protected Au Nanoparticles

采用一步法制备了负电荷磷脂DSPG双层保护的金纳米粒子,并用透射电镜、紫外-可见光谱、X-射线光电子能谱和红外光谱进行了表征.结果表明,所制备的金纳米粒子直径为3～5 nm,具有良好的水溶性和稳定性.

The DSPG bilayer-protected Au nanoparticles were prepared by one-step method and characterized by TEM,UV-Vis spectroscopy,XPS and IR spectroscopy.The results showed that as-prepared Au nanoparticles with 3～5 nm diameters have good water solubility and stability.
