Design of interdisciplinary comprehensive experiment of nano materials and pesticide residue detection
Breaking the barriers between traditional disciplines,promoting the connection between basic research and applied research,and realizing the interdisciplinary are of great significance for cul-tivating high-level and compound innovative talents to meet the needs of national social development.In this paper,silver nanoparticles were prepared by chemical reduction method,and their physical properties were characterized by XPS and SEM.Furthermore,the pesticide fenthion on the surface of red grapes was detected rapidly by using PERS-F700 portable Raman detector and the tested positive report was obtained.The experimental process,involving the preparation,characterization and practi-cal application of materials,blended the relevant knowledge of materials,physics,chemistry and agri-culture.The distinguishing interdisciplinary feature of this comprehensive experimental is conducive to training students' professional skills and improving their comprehensive literacy and scientific research innovation ability.
