为适应化学实验教学现代化需求,该文将CRISPR/Cas12a系统与DNA水凝胶技术结合,设计了基于胶体金试纸条的农业病害检测教学方案。实验利用CRISPR/Cas12a的基因特异性识别能力触发DNA水凝胶可控解聚,释放信号分子人绒毛膜促性腺激素(hCG),通过试纸条实现可视化检测。教学实践表明,该方案整合了分子生物学、材料化学与分析技术,解决了传统教学中依赖大型仪器、成本高昂及跨学科整合不足的问题,为培养学生创新能力和实践技能提供了新途径。
To meet the needs of modernization in chemical experiment teaching,this experiment combines the CRISPR/Cas12a system with DNA hydrogel technology and designs a teaching scheme for the detection of agricultural diseases based on colloidal gold test strips. In the experiment,the gene-specific recognition ability of CRISPR/Cas12a is utilized to trigger the controllable depolyme-rization of the DNA hydrogel,releasing the signal molecule hCG,and realizing visual detection through the test strips. Teaching practice shows that this scheme effectively integrates molecular biology,materials chemistry,and analytical techniques,solving the problems of traditional teaching that rely on large-scale instruments,are costly,and lack interdisciplinary integration. It provides a new approach for cultivating students' innovative abilities and practical skills.
