“…Aptamers serve as an ideal alternative to an antibody for the analysis of pesticide and veterinary drug residues [62]. Aptamers are single-stranded oligonucleotides (RNA or DNA) selected by the Systematic Evolution of Ligands by the Exponential enrichment (SELEX) method [63].…”

The excessive use or abuse of pesticides and veterinary drugs leads to residues in food, which can threaten human health. Therefore, there is an extremely urgent need for multi-analyte analysis techniques for the detection of pesticide and veterinary drug residues, which can be applied as screening techniques for food safety monitoring and detection. Recent developments related to rapid multi-residue detection methods for pesticide and veterinary drug residues are reviewed herein. Methods based on different recognition elements or the inherent characteristics of pesticides and veterinary drugs are described in detail. The preparation and application of three broadly specific recognition elements—antibodies, aptamers, and molecular imprinted polymers—are summarized. Furthermore, enzymatic inhibition-based sensors, near-infrared spectroscopy, and SERS spectroscopy based on the inherent characteristics are also discussed. The aim of this review is to provide a useful reference for the further development of rapid multi-analyte analysis of pesticide and veterinary drug residues.

“…Molecularly imprinted polymers (MIPs) are cross-linked synthetic materials with artificially generated recognition sites able to selectively bind a target molecule [ 85 ]. Molecular imprinting involves the preparation of a “mold”, that is achieved using monomers that are polymerized around the target compound.…”

Detection and monitoring of volatiles is a challenging and fascinating issue in environmental analysis, agriculture and food quality, process control in industry, as well as in ‘point of care’ diagnostics. Gas chromatographic approaches remain the reference method for the analysis of volatile organic compounds (VOCs); however, gas sensors (GSs), with their advantages of low cost and no or very little sample preparation, have become a reality. Gas sensors can be used singularly or in array format (e.g., e-noses); coupling data output with multivariate statical treatment allows un-target analysis of samples headspace. Within this frame, the use of new binding elements as recognition/interaction elements in gas sensing is a challenging hot-topic that allowed unexpected advancement. In this review, the latest development of gas sensors and gas sensor arrays, realized using peptides, molecularly imprinted polymers and DNA is reported. This work is focused on the description of the strategies used for the GSs development, the sensing elements function, the sensors array set-up, and the application in real cases.

“…Furthermore, there are different aspects of the pesticide's sensors such as the biorecognition materials which are aptamer, antibodies, and enzymes and the routine of the chemical reaction between the pesticide's residues and the sensing materials is an affinity biosensor. Affinity biosensors are usually divided into two categories which are the labelled and the label-free biosensor [53], [54]. In the labelled biosensors, labels are usually applied as an easy tool to confirm the interaction and binding that occur between the probe and the target.…”

“…Biosensor has been introduced by Clark in 1962 [98], since that time, the biosensors have been widely used in diverse applications such as pesticides detection [33], food analysis [53], cancer diagnosis [99], and biomedical application [96], [100], etc. Bio-FETs are one of the various kinds of biosensors which consisted of integration between bio-receptors and ion-sensitive field-effect transistor (ISFET).…”

Chemicals and pesticides contamination in the food, drinking water, and environment ecosystem have become one of the most serious problems for human public health in the world due to their large amount used and wide application in the agriculture industry. Therefore, the detection and analysis of contamination in the food and drinking water by using techniques that are simple and suitable for fast screening are important. This review gives an overview of the last trends and recent advances biosensors for chemicals and pesticides detection based on electrochemical, optical and mechanical transducers strategies. Furthermore, the biosensors are classified according to their immobilized biorecognition elements including aptamer, antibodies, enzymes, and molecularly imprinted polymers. The implementation of nanomaterials such as graphene, carbon nanotubes, and metals nanoparticles are also emphasized and discussed in this review, these nanomaterials provides remarkable features to the biosensors such highly sensitive and accurate which allowing efficient pesticides detection. In addition to highlighting and summarizing various novel sensors, this review also provided some drawbacks, challenging, prospects as well as the current efforts to enhanced optical sensors.
