A Mini Review on Electrochemical Nano-biosensors in Detection of Drugs/Pesticides

In last few years, sensing of molecules has gained a huge attention of scientists and researchers. Small molecules (drugs, pesticides, and others) are being consumed directly or indirectly by us in our daily life. Often, these molecules enter the environment and interact with different non-target organisms. Consumption of drugs/pesticides emerged as a major concern for public health, environment, ground-water and agricultural soil. Pesticides can have odd impacts such as degradation of soil properties, environmental pollution, pollution of groundwater as well as the consumption of unwanted drugs can have serious health impacts. Therefore, the sensing of drugs/pesticides plays an important role in detecting and preventing the unwanted usage of drugs/pesticides. Quantitative and qualitative determination of pesticides and drugs can be achieved using electrochemical techniques. This review offers a concise examination of the literature about the electrochemical sensing of drugs and pesticides. The review provides a comprehensive summary of different electrochemical investigations and outlines the reported analytical performance metrics, including limits of detection and linearity ranges. Furthermore, it underscores the progress made in pesticide detection using electrochemical methods for the selected compounds, highlighting the challenges ahead and emphasizing the necessary efforts to develop sensors suitable for in-situ applications.
