仪器分析实验课程建设:表面增强拉曼光谱快速分析食用色素

Course Construction of Instrumental Analysis Experiment:SurfaceEnhanced Raman Spectroscopy for Rapid Detection of Edible Pigments

表面增强拉曼光谱(Surface-enhanced Raman spectroscopy,SERS)由于具有检测速度快、仪器便携性好、灵敏度高及谱图指纹特征丰富等特点,近年来作为一种重要的仪器分析方法已逐步应用于食品安全分析。因此,我们结合前期科研基础,科教融合,设计了“表面增强拉曼光谱快速分析食用色素”实验。学生通过增强基底制备、SERS检测条件的优化、SERS快速分析方法的建立及应用等内容的训练,可充分学习SERS快速分析方法的实验技能,并收获相关的前沿知识,培养实验创新能力。

Surface-enhanced Raman spectroscopy(SERS),as an important instrumental analysis method,has been gradually applied to food safety analysis in recent years due to its advantages in fast detection speed,convenient instrument portability,high sensitivity and abundant fingerprint characteristics.Building on prior research foundations and integrating science with education,we designed an experiment titled“Surface-Enhanced Raman Spectroscopy(SERS)for Rapid Detection of Edible Pigment”.This experiment aims to provide students with hands-on training in the preparation of SERS substrates,optimization of SERS detection,and the development and application of SERS-based rapid analytical methods.By engaging in this experiment,students will not only acquire essential skills in SERS rapid detection but also gain in-depth knowledge of cutting-edge techniques and cultivate their abilities in experimental innovation.
