“…Pesticides can be also classified according to their application; to kill insects (insecticide), weeds (herbicide), fungi (fungicide), nematodes (nematicide), and others. Several methods have been reported in the literature for the detection of pesticides such as fluorescence spectrophotometry [64], gas chromatography with flame ionization detection [65,66], gas chromatography with mass spectrometry detection [67,68], high performance liquid chromatography with fluorescence detection [69,70], and high performance liquid chromatography coupled to mass spectrometry [71,72]. However, in all these cases, the methods require skilled labour, sophisticated instrumentation, and are expensive to run and maintain.…”

Carbon nanotubes have received enormous attention in the development of electrochemical sensors by promoting electron transfer reactions, decreasing the work overpotential within great surface areas. The growing concerns about environmental health emphasized the necessity of continuous monitoring of pollutants. Pesticides have been successfully used to control agricultural and public health pests; however, intense use can cause a number of damages for biodiversity and human health. In this sense, carbon nanotubes-based electrochemical sensors have been proposed for pesticide monitoring combining different electrode modification strategies and electroanalytical techniques. In this paper, we provide a review of the recent advances in the use of carbon nanotubes for the construction of electrochemical sensors dedicated to the environmental monitoring of pesticides. Future directions, perspectives, and challenges are also commented.

“…Classified as hazardous chemical by World Health Organization, Cbz is identified as possible human carcinogens [35]. Spectrophotometry [36,37], chromatography [38,39] and spectrofluorimetry [40,41] are analytical methods frequently used for its determination. Despite their high accuracy and sensitivity, these methods are expensive, require sophisticated instrumentation and sample preparation (involving several time-consuming steps).…”

Fine particles of Ayous sawdust (AS) were successfully modified by maleic anhydride to increase their accumulation capability towards carbendazim (Cbz). For a more efficient use of the biosourced material as electrode modifier for electrochemical detection, the functionalized particles were mixed with carbon nanotubes to yield a conductive composite. After electro-chemical characterization, the modified GCE was applied to Cbz detection. A sensitivity of (2.61 � 0.08) μA M À 1 and a detection limit of 0.04 μM were obtained under optimized experimental conditions. Moreover, the designed sensor was found efficient for Cbz determination in real samples (spring water and commercial pesticide product).

“…Carbendazim has been widely applied in fresh food production for the prevention of numerous pathogens and pests. However, extensive and unreasonable use of carbendazim may result in serious environmental pollution [ 1 ]. Researches demonstrated that carbendazim in the environment causes long-time accumulation in plants that absorb it through their roots and leaves [ 2 ].…”

“…The fluorescent method has good sensitivity and specificity, but it often needs to use commercially unavailable luminescent materials as the optical probe for achieving response to carbendazim. In addition, the fluorescent methods based on common luminescent materials also suffer from the background fluorescence interference from biomacromolecules in food [ 1 ]. The electrochemical sensor has received more attention due to its ease of operation, high sensitivity, high selectivity, low cost, and portability [ 14 ].…”

Graphical abstract An aptasensor for electrochemical detection of carbendazim is reported with mulberry fruit-like gold nanocrystal (MF-Au)/multiple graphene aerogel (MGA) and DNA cycle amplification. HAuCl 4 was reduced by ascorbic acid in a CTAC solution containing KBr and KI and formed trioctahedron gold nanocrystal. The gold nanocrystal underwent structural evolution under enantioselective direction of l -cysteine. The resulting MF-Au shows a mulberry fruit-like nanostructure composed of gold nanocrystals of about 200 nm as the core and many irregular gold nanoparticles of about 30 nm as the shell. The exposure of high-index facets improves the catalytic activity of MF-Au. MF-Au/MGA was used for the construction of an aptasensor for electrochemical detection of carbendazim. The aptamer hybridizes with assistant strand DNA to form duplex DNA. Carbendazim binds with the formed duplex DNA to release assistant strand DNA, triggering one three-cascade DNA cycle. The utilization of a DNA cycle allows one carbendazim molecule to bring many methylene blue–labeled DNA fragments to the electrode surface. This promotes significant signal amplification due to the redox reaction of methylene blue. The detection signal is further enhanced by the catalysis of MF-Au and MGA towards the redox of methylene blue. A differential pulse voltammetric signal, best measured at − 0.32 V vs. Ag/AgCl, increases linearly with the carbendazim concentration ranging from 1.0 × 10 −16 to 1.0 × 10 −11 M with a detection limit of 4.4 × 10 −17 M. The method provides ultrahigh sensitivity and selectivity and was successfully applied to the electrochemical detection of carbendazim in cucumber. This study reports on an ultrasensitive aptasensor for electrochemical detection of carbendazim in cucumber based on mulberry fruit–like gold nanocrystal–multiple graphene aerogel and DNA cycle double amplification.
