摘要 用半胱氨酸做稳定剂,壳聚糖做修饰剂,通过NaBH4还原HAuCl4制备了稳定的金/壳聚糖复合纳米粒子(Au/CS),并研究了反应物配比对金纳米粒子性能的影响.通过紫外-可见、红外、X射线衍射及透射电镜对其结构进行了表征.结果表明,当反应物选择合适的配比时可以合成性能良好的金纳米粒子. Au/CS nanocomposite particles have been synthesized by in-situ reduction of HAuCL with NaBH4as a reductant in aqueous solution, using cysteine（Cys） as a stabilizer and chitosan（CS） as a modifier. The effect of the ratio of reactants on the gold nanoparticles properties was also studied. The gold nanoparticles were characterized by UV-visible （UV-Vis）, fourier transform infrared spectroscopy （FT-IR）, X-Ray diffraction （XRD） and transmission electron microscopy （TEM）. The results indicated that good performance of gold nanoparticles can be synthesized when choosing the appropriate ratio of reactants.
