Recent Advances in the Recognition Elements of Sensors to Detect Pyrethroids in Food: A Review

Abstract

The presence of pyrethroids in food and the environment due to their excessive use and extensive application in the agriculture industry represents a significant threat to public health. Therefore, the determination of the presence of pyrethroids in foods by simple, rapid, and sensitive methods is warranted. Herein, recognition methods for pyrethroids based on electrochemical and optical biosensors from the last five years are reviewed, including surface-enhanced Raman scattering (SERS), surface plasmon resonance (SPR), chemiluminescence, biochemical, fluorescence, and colorimetric methods. In addition, recognition elements used for pyrethroid detection, including enzymes, antigens/antibodies, aptamers, and molecular-imprinted polymers, are classified and discussed based on the bioreceptor types. The current research status, the advantages and disadvantages of existing methods, and future development trends are discussed. The research progress of rapid pyrethroid detection in our laboratory is also presented.

Assessment of developed paper strip based sensor with pesticide residues in different dairy environmental samples

“…Building efficient haptens for immunoassay procedures presents significant hurdles because certain pesticides are hydrophobic compounds. These techniques are relatively restrictive for a wide variety of pesticides since they need specific, unique haptens, which makes them difficult to create due to hapten manufacturing procedures ( Zhang et al, 2022 ). These techniques are sensitive, efficient, and reliable, but they are time-consuming, laborious, require complex sample preparation steps, complicated to employ a single test for a wide range of pesticides and are difficult to use under field conditions.…”

Development of a time-resolved fluorescence microsphere Eu lateral flow test strip based on a molecularly imprinted electrospun nanofiber membrane for determination of fenvalerate in vegetables

“…Preparing antibodies in the mouse body and optimizing storage conditions increase the cost and necessitate the sacrifice of animals. Therefore, to meet the demand for large-scale assessments, it is necessary to establish a fast, sensitive, accurate, and low-cost onsite analysis to monitor food pyrethroids ( 15 ).…”
