Organic sensing element approach in electrochemical sensor for automated and accurate pesticides detection

Abstract

The primary component for human health is food quality and its safety. The world has crossed 8 billion population highlighting major demand to fulfil high consumption food requirement. To overcome food security issue, inorganic farming trend is booming. In the process of boosting agriculture and allied products, unethical practices of using pesticides achieve heights. Protection of plants is necessary from weeds and pests. Thus, in order, to minimize the curb of unwanted growth of weeds and pest attack, pesticides act as an agent for protection and helping for immense production of crops. Therefore, swift and precise detection of harmful pesticides in agriculture products is required in urgent demand. In this review, the distinct organic material-based sensor such as colorimetric sensing, fluorescent sensors, gas chromatography-mass spectrometry, and liquid chromatography, with the organic compounds as sensing elements to monitor pesticides level in distinct samples due to their specificity, reusability, stability, high sensitivity, and selectivity. Apart from it, this study provides a comprehensive overview of the recent major advancement in organic sensing elements in electrochemical sensor pesticides detection based on molecularly imprinted, multimodal sensor polydopamine and conductive polymer at low-cost production.
