Abstract
Despite their important contribution in increasing crops production, most pesticides are harmful to humans and living beings and can persist in the environment over long a long duration. Traditional chromatographic methods of analysis are expensive and cumbersome. Biosensor technology appears therefore as an efficient and economical alternative for fast detection of pesticides. The devices are portable, rapid, and highly sensitive. Other important features of the devices are their relatively high sensistivity and low response time. Enzymatic biosensors for pesticide detection rely either on the inhibition mechanism or on the catalytic activity of the immobilized enzyme toward a specific pesticide. Metal and carbon based nanomaterials are being widely used as immobilization support owing to novel characteristics such as biocompatibility and enhanced electron transfer ability for sensitive electrochemical detection, among others. This review focusses on the electrochemical detection of organophosphorus pesticides, delineating the limit of detection and response time of biosensors toward a wide range of organophosphorus pesticides.
Highlights
The continuous growth of world population has led to an increased use of plant growth regulators, including carbamates and organophosphorus pesticides (OPs) in modern agricultural practices in order to meet the global food demand
This review focuses on the recent techniques described in the literature using enzyme-based electrochemical biosensors in the quantification and analysis of pesticides
Selectivity of the biosensors toward a target analyte is determined by the enzyme recognition layer, while the sensitivity is dependent on the transducer element
Summary
The continuous growth of world population has led to an increased use of plant growth regulators, including carbamates and organophosphorus pesticides (OPs) in modern agricultural practices in order to meet the global food demand. The inhibition of human acetylcholinesterase (AChE) leads to a constant increase of acetylcholine at the neuromuscular junction, initiating severe nerve dysfunction [5]. For this reason, environmental safety and food industries require strict control and quantification of pesticides. The high sensitivity of immobilized enzymes is an important factor in the development of a good biosensor This allows the biosensor to detect one or several analytes in samples. This review focuses on the recent techniques described in the literature using enzyme-based electrochemical biosensors in the quantification and analysis of pesticides Parameters such as the limit of detection and the response time of these techniques are presented and compared
