The present article critically and comprehensively reviews the most recent reports on smart sensors for determining glyphosate (GLP), an active agent of GLP-based herbicides (GBHs) traditionally used in agriculture over the past decades. Commercialized in 1974, GBHs have now reached 350 million hectares of crops in over 140 countries with an annual turnover of 11 billion USD worldwide. However, rolling exploitation of GLP and GBHs in the last decades has led to environmental pollution, animal intoxication, bacterial resistance, and sustained occupational exposure of the herbicide of farm and companies' workers. Intoxication with these herbicides dysregulates the microbiomegut-brain axis, cholinergic neurotransmission, and endocrine system, causing paralytic ileus, hyperkalemia, oliguria, pulmonary edema, and cardiogenic shock. Precision agriculture, i.e., an (information technology)-enhanced approach to crop management, including a site-specific determination of agrochemicals, derives from the benefits of smart materials (SMs), data science, and nanosensors. Those typically feature fluorescent molecularly imprinted polymers or immunochemical aptamer artificial receptors integrated with electrochemical transducers. Fabricated as portable or wearable lab-on-chips, smartphones, and soft robotics and connected with SM-based devices that provide machine learning algorithms and online databases, they integrate, process, analyze, and interpret massive amounts of spatiotemporal data in a user-friendly and decision-making manner. Exploited for the ultrasensitive determination of toxins, including GLP, they will become practical tools in farmlands and point-of-care testing. Expectedly, smart sensors can be used for personalized diagnostics, real-time water, food, soil, and air quality monitoring, site-specific herbicide management, and crop control.

“…In addition, the relation between logarithms at scan rates and E pc (Tafel plot) is expressed as Based on CV experiments with various pH values and scan rates, the reduction potentials of glyphosate are in the range of −0.26 to −0.42 V. It should be noted that the reduction potential of glyphosate is influenced by multiple factors including pH, temperature, scan rate, the choice of sensing material, and the specific electrode employed in the electrochemical measurement. Different studies on glyphosate detection can give the different reduction potentials [53][54][55].…”

Sparked ZnO nanoparticles-based electrochemical sensor for onsite determination of glyphosate residues

et al. 2023

Glyphosate (N-(phosphonomethyl)glycine) is well known nonselective and broad-spectrum herbicide that has been extensively used in agricultural areas around the world to increase agricultural productivity. However, the utilization of glyphosate can cause environmental contamination and health problems. Therefore, the detection of glyphosate with a fast, low-cost, and portable sensor is still important. In this work, the electrochemical sensor has been developed by modifying of working surface on the screen-printed silver electrode (SPAgE) with a mixtures solution between zinc oxide nanoparticles (ZnO-NPs) and poly (diallyldimethylammonium chloride) (PDDA) by the drop-casting process. The ZnO-NPs have been prepared based on a sparking method by using pure zinc wires. The ZnO-NPs/PDDA/SPAgE sensor shows a wide range of glyphosate detection (0 µM - 5 mM). The limit of detection of ZnO-NPs/PDDA/SPAgE is 2.84 µM. The ZnO-NPs/PDDA/SPAgE sensor exhibits high selective towards glyphosate with minimal interference from other commonly used herbicides including paraquat, butachlor-propanil and glufosinate-ammonium. Furthermore, the ZnO-NPs/PDDA/SPAgE sensor demonstrates a good estimation of glyphosate concentration in real samples such as green tea, corn juice and mango juice.

A novel type of nanocomposite‐modified electrodes, synthesized from ZIF67 and mesoporous carbon nitride (CN) featuring a carbonyl heterocyclic ring, were meticulously fabricated via an alkali‐mediated method. This innovative approach led to the construction of high‐performance electrochemical sensors. Utilizing differential pulse voltammetry, these sensors demonstrated significant potential for the precise detection of glyphosate in various aqueous environments. The detection mechanism of this sensor operates through the complexation reaction between Co2+ and glyphosate, resulting in a decrease in the response current. The fabricated material was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray diffraction techniques, X‐ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy to verify its morphology and structure. The results demonstrated that the sensor exhibited high sensitivity, with a detection limit of 0.04 pg/L and a linear range from 10−12–10−5 g/L, showcasing good selectivity for glyphosate. In tests evaluating the sensor's effectiveness for detecting glyphosate in real water samples, recovery rates ranged from 97 %–106 %, further attesting to its high accuracy and practicality.
