Novel Electrochemical Sensor Based on PDA/MXene/MWCNTs/NiCo2O4 Nanocomposites for Rapid, Sensitive, and Selective Detection of Aflatoxin B1

This work established a novel nucleic acid aptamer sensor for the sensitive and selective detection of AFB1 (Aflatoxin B1), which has important implication for food safety. In a word, we synthesized MXene/MWCNTs/NiCo 2 O 4 composite nanomaterials to improve the sensitivity of the aptamer sensor. The...
