This invention belongs to the fields of nanocomposite material preparation and machine learning technology. Specifically, it is a web-based concentration prediction system-assisted method for detecting pefloxacin. Based on the interaction between a ratiometric fluorescent probe (BSA-AuNCs-GTP-Tb) and pefloxacin, it exhibits a variety of visible fluorescent colors under ultraviolet light. The concentration prediction system detects the target object, extracts the fluorescent colors, and identifies the relationship between pefloxacin concentration and color data. The ratiometric fluorescent probe itself has good stability and, compared to single-signal fluorescent probes, is less affected by external factors, exhibiting higher anti-interference capabilities. The concentration prediction system, embedded with deep learning and machine learning, offers high efficiency, accuracy, and stable operation, along with advantages such as simple operation, ease of use, and wide applicability.
