DEVELOPMENT OF ELECTROSPUN MXENE/POLYVINYLIDENE FLUORIDE NANOFIBER COMPOSITES APTASENSOR FOR EFFICIENT DETERMINATION OF OCHRATOXIN A

Ochratoxin A (OTA) foodborne mycotoxin is an ongoing global concern with 25% of the world’s harvested crops being contaminated each year, leading to wide toxicological effects to human and animal health while contributing to billions of dollars losses in agricultural and food-based industries. Current analytical methods used for the detection of food pollutants suffer from sophisticated instrumentation, complicated operations, poor sensitivity, and selectivity with time-consuming detection processes. In this thesis, a simple and ultrasensitive aptasensor electrode, viz. electrospun polyvinylidene fluoride (PVDF)/MXene (Ti3C2Tx) composite fiber, was developed for efficient detection of OTA.
