The surface-enhanced Raman scattering (SERS) studies of anserine (beta-alanyl-N-methylhistidine) was carried out on colloidal silver nanoparticles to understand its adsorption characteristics. The experimentally observed Raman bands were assigned based on the results of DFT calculations. The studies suggest that the interaction of anserine is primarily through the carboxylate group with the imidazole ring in an upright position with respect to the silver surface. Concentration dependent SERS studies suggest a change in orientation at sub-monolayer concentration.
开展了鸡氨酸（β-丙氨酰-N-甲基组氨酸）在胶体银纳米粒子上的表面增强拉曼散射（SERS）研究，以了解其吸附特性。根据 DFT 计算的结果对实验观测到的拉曼带进行了归属。研究表明，鸡氨酸的相互作用主要是通过羧酸盐基团与银表面垂直的咪唑环进行的。浓度依赖性 SERS 研究表明，在亚单层浓度下，取向会发生变化。
