AI Technical Summary

Technical Problem

Existing technologies for TC detection are complex and costly, lacking simple and rapid detection methods, making it difficult to achieve accurate quantitative detection of TCs in food and water environments.

Method used

Using BSA-AuNCs@ZIF-8 probes, TCs were detected by ratiometric fluorescence method after loading BSA-AuNCs into a ZIF-8 framework. This was combined with portable cotton swabs and a UV flashlight to achieve rapid semi-quantitative detection.

Benefits of technology

This method enables simple and rapid detection of TCs without the need for complex instruments, with response performance consistent with that of solution systems, and is suitable for TC detection in food and aquatic environments.
