摘　　要：设计了一个还原法制备金溶胶,并进一步合成具有双面神结构的金-聚丙烯酸铵纳米粒子的本科生化学实验。首先,采用溶胶法合成金纳米粒子,然后,聚丙烯酸通过异向生长与金纳米粒子形成具有双面神结构的纳米粒子。本实验可以锻炼学生制备纳米材料的能力,熟悉金纳米粒子的制备方法及其纳米尺度的特殊性质,并掌握仪器设备的使用,认识纳米尺度可操控材料的结构,得到金-聚丙烯酸铵双面神纳米粒子,使学生进一步了解科学前沿,提升科学素养。An undergraduate experiment was designed to prepare gold sol by reduction method and further synthesize gold-ammonium polyacrylate Janus nanoparticles. Firstly, gold nanoparticles were synthesized by sol method. Then, polyacrylic acid was anisotropically grown on one side of gold nanoparticles to form nanoparticles with double-sided god structure. This experiment can exercise the students’ ability to the preparation of nanomaterials, familiar with the preparation of gold nanoparticles and their special properties of nanometer scale, and master the use of instruments and equipment, understanding that the structure can be controlled in nanoscale, finally obtain the gold-ammonium polyacrylate Janus nanoparticles, causes the student to learn more about science frontiers, promote scientific literacy.
