A novel three-dimensional network of CuCr2O4/CuO nanofibers for voltammetric determination of anticancer drug methotrexate

Electrochemical Sensor for the Determination of Methotrexate Based on MOF-Derived NiO/Ni@C-Poly(isonicotinic acid)

“…Therefore, the oxidation of MTX participates in an equal number of protons and electrons. The proposed oxidation mechanism of MTX can be perceived in Scheme …”

A copper oxide nanorod derived metal–organic framework nanocomposite: a robust and sensitive electrocatalyst for the detection of furazolidone

“…This can be due to the saturation of the active sites of the electrode surface at high concentrations of FUZ and create kinetic limitations. 42 The detection limit of this method, based on the signal-tonoise ratio definition (S/N = 3s/m, where s is the standard deviation of the blank solution and m is the slope of the calibration curve), was determined as 2.3 nmol L À1 FUZ.…”

Simple, low-cost and sensitive electrochemical sensing of antineoplastic drug amethopterin based on a nanocarbon black modified electrode

“…12,13 Recently, the electrochemical technologies have received considerable attention and some related methods have been developed for sensing ATP based on their prominent advantages of simplicity, sensitivity, accuracy and ease of eld applications. [14][15][16] For instance, Foroughi et al 13 synthesized cerium-ZnO nanoowers to fabricate an electrochemical sensor of ATP and the work demonstrated that the cerium-ZnO electrode shows a detection limit (LOD) of 6.3 nM; while Fathi et al 17 constructed a CuCr 2 O 4 /CuO carbon paste electrode for the electrochemical detection of ATP in the presence of IL; a linear range from 0.1 to 300.0 mM and LOD of 0.025 mM were achieved successfully under the optimized conditions. In another interesting study, Shahrokhian et al 18 prepared a 3D porous graphene-carbon nanotube network and successfully used it for the electrochemical detection of ATP with good sensitivity and high accuracy.…”
