Abstract: Based on the principles of physical chemistry, this study integrates knowledge from organic chemistry, analytical chemistry, and computer science to develop an “Intelligent detection system for metal ions and pesticide residues” using a high-precision starch-based carbon dot sensor chip. The system employs a low-cost and safe hydrogel matrix, with corn starch serving as the raw material for chip fabrication. Combined with a self-developed Android/HarmonyOS application—written in Java within the Android Studio environment—the system enables efficient and economical intelligent analysis and monitoring of metal ions and pesticide residues. This approach is user-friendly, innovative, and practical, enhancing both student engagement and the educational value of experimental teaching, while offering a valuable case study for interdisciplinary teaching reform.
