Multiple Recognition-Based Sensor for Pesticide Residues

Abstract

The use of pesticides is gradually increasing to improve the yield and quality of crops. However, excessive pesticide use has led to a dramatic pollution increase in the environment and agricultural products, posing severe human health risks. Therefore, rapid, sensitive pesticide detection is essential. Various pesticides detection methods and products have been developed in recent years. This brief review summarized the point-of-care testing (POCT) detection of pesticides based on multiple recognition, including protein-, aptamer-, nanomaterial-, and macrocycle-based recognition. The review aimed to address the growing demands for regulating and destroying pesticides or other adverse agriculture-related applications in the real world.

The porous hollow cobalt-based oxides encapsulated with bimetallic PdAu Nanoparticles of electrochemical biosensor for highly sensitive pesticides detection

“…Currently, traditional pesticide detection methods included mass spectrometry (MS) [7], high performance liquid chromatography [8] and gas chromatography-mass spectrometry [9]. These methods can achieve qualitative and quantitative analysis, but cannot meet the point-of-care testing detection of pesticides [10][11][12]. Notably, AChE inhibitionbased biosensors have gotten attractive attention due to their simplicity, high sensitivity, and relatively low cost [13].…”
