纳米前沿与法庭科学融合下的化学实验教学设计——以“碳点的合成、表征和应用”为例

Design of chemical experiment teaching based on fusion of nano frontier and forensic science:Synthesis,characterization and application of carbon dots

该文以碳点的合成、表征和应用为例,进行了纳米前沿与法庭科学融合下的化学实验教学设计。该实验以碳点在手印显现中的实际应用为核心,以解决碳点在手印显现应用中面临的问题为导向,充分阐释了实验背景原理,系统梳理了实验内容方法,明确细化了实验教学实施,体现了实验选题的创新性、实验背景的科学性和实验内容的实践性。通过开展该实验教学活动,可以培养学生的自主学习能力,锻炼学生的实验技能,提升学生实验数据处理水平,起到增强学生创新意识和综合素质的作用。

This article takes the synthesis,characterization and application of carbon dots as an example to design chemical experimental teaching by integrating nanotechnology and forensic science.This experiment focuses on the practical application of carbon dots in fingerprint development and the ways to solve the problems faced by carbon dots in this application.It fully explains the principle of experimental background,systematically arranges the experimental content and methods,and clearly refines the implementation of experimental teaching,which reflects the innovation of topic selection,the scientificity of experimental background,and practicality of experimental content.By conducting this experimental teaching activity,the self-learning ability,experiment skill,and experiment data processing level of the students can be improved.Accordingly,their innovative consciousness and comprehensive quality can be enhanced.
