Abstract:

The extensive use of organophosphorus pesticides (OPs) causes serious environmental pollution and poses a serious health risk to food and drinking water. Electrochemical biosensors using acetylcholinesterase (AChE) as a recognition element can detect OPs quickly, efficiently, and accurately. The use of carbon nanotubes (CNTs) composites can improve the effectiveness of AChE electrochemical biosensors for OPs detection. This review outlines the use of composites consisting of CNTs in combination with organic matter, metal nanoparticles, metal oxide nanoparticles, and ionic liquids in AChE electrochemical biosensors. The advantages and disadvantages, as well as issues for future commercial applications, of CNTs composites in AChE electrochemical biosensors are summarized.
