Abstract
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.
Highlights
In the last three decades, the detection of hazardous chemicals and pesticides has been attracting both industrial and academia attention
This review has highlighted some drawbacks of the electrochemical biosensors especially in the process of converting the biosensors to be used as portable devices
While remarkable progress has been made towards improving the sensitivity of the detection through the utilization of nanomaterials, there are opportunities to enhance the reusability and portability of the devices
Summary
In the last three decades, the detection of hazardous chemicals and pesticides has been attracting both industrial and academia attention. Ba Hashwan et al.: Recent Progress in the Development of Biosensors for Chemicals and Pesticides Detection analysis have been carried out using current analytical methods including mass spectrometry (MS), high-performance liquid chromatograph (HPLS), and gas chromatograph (GC) [1], [13]. These techniques have demonstrated powerful trace analysis with high sensitively and excellent reproducibility, but there are some drawbacks including time consuming, sophisticated equipment and long sample preparation process which are defense the on-situ and real time detection [14]. We investigate and discuss the current techniques used for chemicals and pesticides detection, taking into account the use of recognitions elements, including the enzymes, antibodies, aptamers, and molecular imprinted polymers
