“…These results suggest that the electroreduction of IMP converts its nitro group (R ̶ NO 2 ) to hydroxylamine (R ̶ NHOH) in two steps (Scheme 2), consistent with previous literature reports. 29,46,48 Hydroxylamine may undergo further reduction to form amine derivatives (R-NH 2 ). 9,49 However, this reduction step aligns with the hydrogen evolution signal, making it imperceptible in the voltammetric response.…”

The electrocatalytic activity of silver towards imidacloprid reduction was demonstrated at both macro- and nano-scales. Coupled with the advantages of microscopic electrodes, this has led to the development of a highly-sensitive and selective electrochemical sensor for imidacloprid detection. This sensor utilizes silver nanoparticle-decorated carbon fiber microelectrodes (AgNPs/CF) fabricated through a single-step electrodeposition. Employing AgNPs/CF, the linear range, sensitivity, and limit of detection (3SB/m) were determined to be 0.0–0.40 mM, 2.98×10−8 ± 0.10×10−8 A mM−1, and 60.4 nM, respectively. The sensor was successfully applied to detect imidacloprid directly in various water samples without the need for sample preparation, demonstrating ca. 100% recoveries. Moreover, the sensor was applied to analyze imidacloprid release from contaminated soil samples, revealing Langmuir characteristics of the desorption process.

“…However, these approaches have drawbacks such as being time consuming, needing highly skilled personnel, and requiring the use of expensive instruments. Therefore, advanced approaches for the determination of pesticides were reported using sensor-based techniques such as electrochemical impedance spectroscopy (EIS) ( Lahrich et al, 2016 ), differential pulse voltammetry (DPV) ( Farahi et al, 2014 , 2015 , 2016 ), square wave anodic stripping voltammetry (SWASV) ( El Harmoudi et al, 2013 ), differential pulse anodic stripping voltammetry (DPASV) ( Elkasmi et al, 2016 ), and square wave voltammetry (SQW) ( Ajermoun et al, 2019 , 2020 ; El Harmoudi et al, 2017 ; El Mhammedi et al, 2010 ; El Mhammedi et al, 2007a , 2007b ; El Mhammedi et al, 2008 ; El Mhammedi et al, 2009 ). These electrochemical techniques are very sensitive and offer several advantages including low-cost, simplicity, rapid operation and low detection limits compared to the conventional chromatographic methods ( Laghrib et al, 2020 ).…”

“…To create biorecognition element-free neonicotinoid sensors, researchers have used a variety of materials including bismuth, β-cyclodextrin (β-CD), silver, and metal–organic frameworks (MOFs) to directly reduce/oxidize the pesticides to create a measurable electrochemical signal. However, the construction of such sensors is tedious, requiring sputter coating, hydrothermal nanoparticle synthesis, nanoparticle chemical coprecipitation synthesis, magnetic separation, centrifugation, and solvent soaking/rinsing, which elicits the need for a simple, conductive, and direct-write fabrication method that does not require various nanoparticle depositions or metal frameworks. − Some manuscripts have even attempted to monitor all four of these neonicotinoids, but significant matrix effects and interference from metal cations and surface-active organic compounds were observed . To correct this, a tedious and expensive solid-phase extraction (SPE) procedure was employed, and the level of quantification was only in the microgram range (9–17 μg/L).…”

Electrochemical Sensing of Neonicotinoids Using Laser-Induced Graphene

Neonicotinoids are the fastest-growing insecticide accounting for over 25% of the global pesticide market and are capable of controlling a range of pests that damage croplands, home yards/gardens, and golf course greens. However, widespread use has led to nontarget organism decline in pollinators, insects, and birds, while chronic, sublethal effects on humans are still largely unknown. Therefore, there is a need to understand how prevalent neonicotinoids are in the environment as there are currently no commercially available field-deployable sensors capable of measuring neonicotinoid concentrations in surface waters. Herein, we report the first example of a laser-induced graphene (LIG) platform that utilizes electrochemical sensing for neonicotinoid detection. These graphene-based sensors are created through a scalable direct-write laser fabrication process that converts polyimide into LIG, which eliminates the need for chemical synthesis of graphene, ink formulation, masks, stencils, pattern rolls, and postprint annealing commonly associated with other printed graphene sensors. The LIG electrodes were capable of monitoring four major neonicotinoids (CLO, IMD, TMX, and DNT) with low detection limits (CLO, 823 nM; IMD, 384 nM; TMX, 338 nM; and DNT, 682 nM) and a rapid response time (∼10 s) using square-wave voltammetry without chemical/biological functionalization. Interference testing exhibited negligible responses from widely used pesticides including the broad-leaf insecticides parathion, paraoxon, and fipronil, as well as systemic herbicides glyphosate (roundup), atrazine, dicamba, and 2,4-dichlorophenoxyacetic acid. These scalable, graphene-based sensors have the potential for wide-scale mapping of neonicotinoids in watersheds and potential use in numerous electrochemical sensor devices.
