Biosensors for Pesticide Detection: New Trends

Abstract

Due to the large amounts of pesticides commonly used and their impact on health, prompt and accurate pesticide analysis is important. This review gives an overview of recent advances and new trends in biosensors for pesticide detection. Optical, electrochemical and piezoelectric biosensors have been reported based on the detection method. In this review biosensors have been classified according to the immobilized biorecognition element: enzymes, cells, antibodies and, more rarely, DNA. The use of tailor-designed biomolecules, such as aptamers and molecularly imprinted polymers, is reviewed. Artificial Neural Networks, that allow the analysis of pesticide mixtures are also presented. Recent advances in the field of nanomaterials merit special mention. The incorporation of nanomaterials provides highly sensitive sensing devices allowing the efficient detection of pesticides

Perspective potential of polymer-based biosensor chips in food industry and clinical diagnostics

“…Biosensors present a novel and cost effective method for detection not only the microbial pathogens, but also allergens and organic, toxic compounds in food, such as pesticides [49]. Fluorescence-labelled biosensor also found their application in food industry.…”

Application of Modern Biosensors Methods in Ecotoxicological Monitoring of Some Toxins of Natural (Micotoxins) and Antropogenic (Pesticides) Origin. Part 2. Pesticides

“…Інші методи, основані на інгібуванні фер-ментів, іммунологічних технологіях, а також на принципах біосенсорики, постійно вдоско-налюються, що відображено в оглядах та екс-периментальних статтях [54][55][56].…”

Synthesis of Polyaniline Based Nanocomposite Graphite Paste Electrode Modified with and Without Rice Husk for Sensor Application: A Comparative Study

“…The proposed Synthesis of Polyaniline Based Nanocomposite Graphite Paste Electrode Modified with and Without Rice Husk for Sensor Application: A Comparative Study potentiometric method has been validated by using inductively coupled plasma-atomic emission spectrometry (ICP-AES). To the best of our knowledge, this is the second instance wherein rice husk has been employed as a modifier for sensing method [3][4][5][6]. The role of PANI is that to provide conductivity.…”
