AB  - Dimethoate (DMT) is an organophosphate pesticide (OP), which is widely used against insects and mites and their control in agriculture. As other OPs, DMT is also an inhibitor of acetylcholinesterase, which is responsible for the disabling of cholinesterase required for the functioning of the central nervous system. This pesticide can invade living cells of the human body through contact or ingestion. We report an electrochemical sensor based on a layer by layer deposition of PDAC/GO on silver electrodes. The sensor fabrication, physical characterization i.e. Raman spectroscopy and scanning electron microscopy of PDAC/GO based films, and its electrochemical characterization are discussed. The detection of DMT by analyzing electrochemical measurements including cyclic voltammetry and impedance spectroscopy shows that functionalization using layer by layer deposition improves electrochemical response and presents a basis for detection of DMT. The highest response is observed in the case of only one PDAC/GO layer which is attributed to the properly balanced interaction between DMT and PDAC/GO layer, and the increase of electrical resistivity of the PDAC/GO layer with its thickness. © 2019 IEEE.

AB  - Extensive use of pesticides and their accumulation in the environment requires swift actions in terms of their removal, detection, and quantification. Currently, golden standard methods used for quantification of pesticides require expensive instrumentation and are not suitable for quick measurements outside of properly equipped laboratory. Here we investigate the detection of dimethoate (DMT) using PDAC/reduced graphene oxide (rGO)-modified Ag electrodes. The sensor performance depends on the temperature used for the reduction of graphene oxide (GO) in PDAC/GO bi-layer on Ag electrode. Using this combination of nanomaterials, we show the quantification of DMT with either voltammetry or impedance spectroscopies. The former approach relies on direct electrochemical transformations of DMT which are observed at relatively high anodic potential around 0.3 V vs. saturated calomel electrode. Impedance spectroscopy shows complex behavior with increasing DMT concentration, but seems to be rather sensitive to low DMT concentrations. These results present a possible direction to the development of highly efficient electrochemical sensors for pesticide detection. © 2019 IEEE.
