以2-巯基-4-甲基-5-噻唑乙酸（MMTA）为稳定剂，硼氢化钠（NaBH 4）为还原剂制备了水溶性金纳米粒子（AuNPs）。通过透射电子显微镜（TEM）、紫外-可见吸收光谱和傅里叶变换红外光谱（FTIR）对AuNPs产物进行分析。TEM图像显示颗粒分散良好，其平均粒径约为5 nm。UV-vis吸收和FTIR光谱证实MMTA-AuNP被存在于AuNP表面上的羧酸根离子稳定。
Water-soluble gold nanoparticles (AuNPs) were prepared using 2-mercapto-4-methyl-5- thiazoleacetic acid (MMTA) as a stabilizing agent and sodium borohydride (NaBH4) as a reducing agent. The AuNPs product was analyzed by transmission electron microscopy (TEM), UV-vis absorption spectroscopy and Fourier transform infrared spectroscopy (FTIR). The TEM image shows that the particles were well-dispersed and their average particle size is about 5 nm. The UV-vis absorption and FTIR spectra confirm that the MMTA-AuNPs was stabilized by the carboxylate ions present on the surface of the AuNPs.
