Chemical safety using functionalized carbon nanomaterials: neutralization and detection of organophosphorus compounds

“…Methyl parathion has also been detected by sensors based on MIPs (Molecularly Imprinted Polymer) associated with the CNTs. MIPs have recognition cavities that are shape-selective 203 and can mimic biological receptors and their functions, with the advantage of more stability. 204 Another work of Guoyue Shi's group 205 reported the detection of this pesticide through a MIP/ MWCNT-based sensor.…”

Non-enzymatic electrochemical sensors based on nanomaterials for detection of organophosphorus pesticide residues

“…Anirudhan et al 148 synthesized copolymers of 3-thiophene acetic acid and 3,4-ethylene dioxythiophene on multi-walled carbon nanotubes to improve the conductivity of the sensing device, which is prepared by in situ chemical oxidative polymerization, leading to the construction of a molecularly imprinted sensor with good conductivity and a large surface area, that can detect chlorpyrifos. Copper nanoparticles modified on vinyl-functionalized graphene and molecularly imprinted polymers fabricated on them were studied by Sooraj et al 149 The sensor uses methyl parathion as a template, methacrylic acid as a monomer, and vinyl-functionalized graphene modified with copper nanoparticles, synthesized by reducing propane copper complexes (DAPCu) to increase the performance of the sensor. Bölükbaşı et al 150 fabricated multi-walled carbon nanotubes (MWCNTs)/molybdenum disulfide nanoparticle (MoS 2 NP) nanocomposites, which have excellent electron transfer capacity and specific surface area, properties that are of interest, by a hydrothermal method to modify glassy carbon electrodes, and then used parathion as the template and pyrrole as the monomer, to make a molecularly imprinted electrochemical sensor that could detect parathion.…”

An Electrochemical Sensor for Sulfadiazine Determination Based on a Copper Nanoparticles/Molecularly Imprinted Overoxidized Polypyrrole Composite

“…CuNPs exhibit good conductivity, high chemical and mechanical stability, and a high specific surface area that makes them suitable for electrochemical sensors. Some researchers have proven that copper nanoparticles electrochemically deposited on the MIP surface are useful in the sensitive detection of drugs and pollutants [ 31 , 32 , 33 ].…”
