Fabrication of a nanostructure-based electrochemical sensor for simultaneous determination of N-acetylcysteine and acetaminophen

Kinetic Spectrophotometric Determination of N-acetyl-L-cysteine Based on the Reduction of Copper(II)-neocuproine Reagent

“…1 The European Pharmacopeia recommended iodimetric titration for pharmaceutical formulations analysis. 2 Other reported methods described in the literature comprise: titrimetry, 3,4 spectrophotometry, [5][6][7][8][9] fluorimetry, [10][11][12] chromatography, 13,14 potentiometry, 15 conductometry 16 and voltametry [17][18][19] for the determination of NAC in pure form, in dosage forms and in biological samples.…”

Electroanalysis and Simultaneous Determination of 6-Thioguanine in the Presence of Uric Acid and Folic Acid Using a Modified Carbon Nanotube Paste Electrode

“…Carbon paste electrode (CPE) is a special kind of heterogeneous carbon electrode consisting of mixtures prepared from carbon powder and a suitable water-immiscible or non-conducting binder. [24][25][26] The use of carbon paste as an electrode was initially reported in 1958 by Adams. 27 In later researches a wide variety of modifiers [28][29][30][31] have been used with these versatile electrodes.…”

Evaluation of the degradation of acetaminophen by the filamentous fungus Scedosporium dehoogii using carbon-based modified electrodes

“…As it is well known that the oxidation of APAP involves protons [34][35][36][37], the redox system should be affected by a change in solution pH value. To get an insight into the electrochemical behavior of APAP on p-NiTSPc modified CFME, the effect of pH on the electrode response was studied in the pH range from 3.…”

“…Of particular interest are carbon-based modified electrodes that are easy to prepare, inexpensive, and generally give rise to reproducible signals [30,31]. Some recent reports on the detection of APAP by means of carbon-based electrodes include the use of glassy carbon coated by various modifiers [32,33] and mainly the exploitation of chemically modified carbon paste electrodes [34][35][36][37][38][39][40]. In the special case of stripping voltammetry exploiting these modified electrodes, typical limits of detection are between 10 −5 and 10 −10 M [30,[34][35][36][37].…”
