碳量子点的制备及其在生物巯基化合物检测中的应用——推荐一个大学化学研究型综合实验

doi:10.3866/PKU.DXHX202105020

Abstract

Abstract:

A comprehensive chemical experiment is introduced in the paper, including the synthesis, characterization of carbon quantum dots and the fluorescence detection of biothiol. This experiment not only makes students understand the hot spots in the frontier of science, but also enables students to master the structures, principles and operational skills of UV-Vis and fluorescence spectrometers, which are helpful for the innovative consciousness and comprehensive application ability training.

Key words: Carbon quantum dot, Biothiol, Fluorescence detection, Comprehensive experiment
