摘要:

近年来,大学生综合创新实验在丰富实验教学内容、探索新型教学模式、提高学生创新实践能力和综合素养等方面发挥着越来越重要的作用。然而,由于大学生有限的时间和精力,同时大多数学生对创新实验的背景及内容了解不深,因此,如何提出一个时长合适、难度适中,并且能够引发学生兴趣的综合创新实验非常重要,也是实现实验教学培养目标的关键之一。基于此,结合“聚集诱导发光”这一国人引领的学术前沿研究热点,通过聚集诱导发光材料四苯基乙烯与传统荧光材料4', 5'-二溴荧光素的光物理性能对比及其在指纹成像中的应用研究,进一步丰富创新实验教学内容。在拓展学生对相关前沿研究和背景知识了解的同时,加强学生对荧光光谱仪等仪器的掌握,提高其实践操作水平。本综合创新实验的实施也能够培养和提高学生发现问题、解决问题的水平和能力,为提升其科研素养和养成创新思维等提供新的探索思路。

Abstract:

Recently, the comprehensive innovation experiments for undergraduates played important roles in enriching the teaching contents, establishing new teaching models, and enhancing students' innovative ability. However, due to the limited time for undergraduates, and their lack of understanding of the background and content of innovation experiments, how to propose a proper comprehensive innovation experiment is very important, and it is also one of the key steps to realize the teaching and training goals. Based on these considerations, the research on "aggregation-induced emission" (AIE) is proposed as a comprehensive innovation experiment. By comparing the photo-physical properties of AIE active tetraphenylethylene and traditional fluorescent material of 4', 5'-dibromofluorescein, and investigating its potential application in fingerprint imaging, it is anticipated that the content in innovative laboratory teaching can be well enriched. While expanding students' understanding of the relevant background knowledge, their practical ability in fluorescence spectrometers and some other instruments can also be improved. The implementation of this comprehensive innovation experiment can then cultivate and improve students' ability to discover and solve problems, and finally provide new exploration ideas for their scientific training and innovative thinking.

Key words: Comprehensive innovation experiment, Aggregation-induced emission, Fluorescence, Latent fingerprints imaging
