摘　　要：以手性离子液体(1-乙基-3-甲基咪唑L-酒石酸盐,EMIML-Tar)为修饰剂,硼氢化钠为还原剂,氯金酸为原料合成金纳米粒子.对影响合成的条件进行优化,并将所合成的金纳米粒子用于D-和L-酪氨酸的手性识别.实验结果表明:D-酪氨酸和L-酪氨酸与金纳米粒子混合后产生的紫外可见光谱图有明显差异.Gold nanoparticles were synthesized by using sodium borohydride as the reducing agent, chloroauric acid as the raw material, and a chiral ionic liquid （1-ethyl-3-methylimidazole L-tartrate, EMIML-Tar） as the modifier. The synthesis condition was optimized, and synthesized gold nanoparti- cles were further applied in the chiral recognition of tyrosine enantiomers. The experimental results showed that mixed solutions of gold nanoparticles with D-tyrosine and L-tyrosine had obvious differ- ences in their ultraviolet-visible spectra.
