AI Technical Summary

Technical Problem

Current methods for detecting aflatoxin B1 (AFB1) are costly, complex, and time-consuming, making them unsuitable for widespread use in developing countries, and existing MOF-based sensors operate on a 'turn-off' sensing mechanism that lacks sensitivity and selectivity.

Method used

A method using an electrospun nanofiber membrane loaded with NH2-MIL-53(A1) that operates on a 'turn-on' fluorescence principle, utilizing NH2-MIL-53(A1) prepared through a specific synthesis process and applied in a flexible, portable sensor for rapid detection.

Benefits of technology

Provides a cost-effective, sensitive, and selective detection of AFB1 with reduced time and equipment requirements, suitable for on-site qualitative and quantitative analysis.
