“…10,13 Among them, the rapid detection method established with broad-specicity antibodies (Abs) as core recognition elements provides a new idea for the preliminary detection of a large number of samples. 14 Abs achieve broad-specicity recognition by recognizing the common structure of one or several kinds of substances, in which the common structure is an antigen or a hapten. 15 Xu et al [15][16][17] Based on these studies, they established direct competitive enzyme-linked immunoassay (dcELISA), direct competitive chemiluminescence enzyme-linked immunoassay (dcCLEIA), uorescence polarization immunoassay (FPIA), direct competition time-resolved uorescence immunoassay (dcTRFIA) and other immunoassay methods.…”

“…Employing wearable plant sensors for on‐site detection of pesticides, plant hormones, VOCs and harmful gas molecules on crops samples is crucial for enhancing precision agriculture and post‐harvest management. Electrochemical biosensors commonly employed for pesticide detection often use enzymes, such as organophosphorus hydrolase (OPH) (Zhao et al ., 2020), or antibodies, such as broad‐spectrum antibodies (Abs) (Dong et al ., 2021). However, these sensors are limited by their vulnerability to non‐specific interactions, storage constraints and challenges related to long‐term stability.…”

SummaryPlant health is intricately linked to crop quality, food security and agricultural productivity. Obtaining accurate plant health information is of paramount importance in the realm of precision agriculture. Wearable sensors offer an exceptional avenue for investigating plant health status and fundamental plant science, as they enable real‐time and continuous in‐situ monitoring of physiological biomarkers. However, a comprehensive overview that integrates and critically assesses wearable plant sensors across various facets, including their fundamental elements, classification, design, sensing mechanism, fabrication, characterization and application, remains elusive. In this study, we provide a meticulous description and systematic synthesis of recent research progress in wearable sensor properties, technology and their application in monitoring plant health information. This work endeavours to serve as a guiding resource for the utilization of wearable plant sensors, empowering the advancement of plant health within the precision agriculture paradigm.

“…Organophosphorus pesticides are some of the most commonly used throughout the agriculture industry to control pests and diseases and increase crop production. As such, there have been various electrochemical biosensors designed for their detection utilising different recognition elements such as antibodies [66], nanozymes [67], enzymes [68], and aptamers [69]. The aptamer-based system reported by Fu et al utilised reduced graphene oxide (rGO) as a base for the immobilisation of copper nanoparticles (CuNPs) and the aptamer element.…”

Robust, reliable, and affordable analytical techniques are essential for screening and monitoring food and water safety from contaminants, pathogens, and allergens that might be harmful upon consumption. Recent advances in decentralised, miniaturised, and rapid tests for health and environmental monitoring can provide an alternative solution to the classic laboratory-based analytical techniques currently utilised. Electrochemical biosensors offer a promising option as portable sensing platforms to expedite the transition from laboratory benchtop to on-site analysis. A plethora of electroanalytical sensor platforms have been produced for the detection of small molecules, proteins, and microorganisms vital to ensuring food and drink safety. These utilise various recognition systems, from direct electrochemical redox processes to biological recognition elements such as antibodies, enzymes, and aptamers; however, further exploration needs to be carried out, with many systems requiring validation against standard benchtop laboratory-based techniques to offer increased confidence in the sensing platforms. This short review demonstrates that electroanalytical biosensors already offer a sensitive, fast, and low-cost sensor platform for food and drink safety monitoring. With continued research into the development of these sensors, increased confidence in the safety of food and drink products for manufacturers, policy makers, and end users will result.
