Nonenzymatic electrochemical sensor based on CuO-TiO2 for sensitive and selective detection of methyl parathion pesticide in ground water

3D Hydrogen Titanate Nanotubes on Ti Foil: A Carrier for Enzymatic Glucose Biosensor

“…Nanostructured TiO 2 has important applications in optoelectronic devices, sensors and energy conversion devices [17][18][19]. It has also been reported that TiO 2 nanocomposites provide a new way to immobilize glucose oxidase and prepare biosensors [20].…”

Zirconia nanocomposites with carbon and iron(iii) oxide for voltammetric detection of sub-nanomolar levels of methyl parathion

“…These include gold, 15,16 silver, zinc oxide, 1,17 zirconia nanoparticles [18][19][20] and other metal oxides. 21,22 Among all of these nanoparticles, the use of zirconia is of particular interest due to its affinity towards the phosphate group present in MP. These nanoparticles themselves have a large surface area and by virtue of their affinity towards the phosphate group, offer a high level of sensitivity and selectivity.…”

Construction of a luminescent sensor based on a lanthanide complex for the highly efficient detection of methyl parathion

“…33 As one of the most toxic OPs, methyl parathion (O,O-dimethyl O-4-nitrophenyl phosphorothionate, MP, Scheme 1(a)) was clas-sied as 'Category Ia' (extremely toxic) by the World Health Organization (WHO) and 'Toxicity Category I' (most toxic) by the United States Environmental Protection Agency (USEPA). [34][35][36] However, its detection by uorescent methods was seldom reported, and almost all of them utilized enzymes as catalyst, 37,38 which made the analytical process complex and expensive. Based on the above analysis, herein, a luminescent lanthanide complex of HL-Eu 3+ with red uorescent emission was synthesized and chosen as the sensing and detecting units for MP.…”
