A detailed study on the synthesis of spherical and monodispersed gold nanoparticles (AuNPs) using all of the 20 naturally occurring α-amino acids has been reported. The synthesized nanoparticles have been further characterized using various techniques such as absorbance spectroscopy, transmission electron microscopy, dynamic light scattering and nuclear magnetic resonance. Size control of the nanoparticles has been achieved by varying the ratio of the gold ion to the amino acid. These monodispersed water soluble AuNPs synthesized using non-toxic, naturally occurring α-amino acids as reducing and capping/stabilizing agents serve as a remarkable example of green chemistry.
已有报告对使用全部20种天然存在的α-氨基酸合成球形且单分散的金纳米颗粒（AuNPs）进行了详细研究。已使用多种技术对合成的纳米颗粒进行了进一步表征，如吸光光谱法、透射电子显微镜、动态光散射和核磁共振。通过改变金离子与氨基酸的比例实现了纳米颗粒的尺寸控制。这些使用无毒的天然存在的α-氨基酸作为还原剂和封端/稳定剂合成的单分散水溶性AuNPs是绿色化学的一个显著例子。
