Electrochemical sensor for acetaminophen based on an imprinted TiO2 thin film prepared by liquid phase deposition

Poly(taurine)/MWNT-modified glassy carbon electrodes for the detection of acetaminophen

“…The cyclic voltammogram (e) of the poly(taurine)/MWNTmodified electrode in pH 7.38 phosphate buffer without acetaminophen is featureless. Based on the electrochemical behavior of acetaminophen on the modified electrodes reported previously [31][32][33][34][35][36][37][38][39][40] and our experimental results, the anodic wave at 0.37 V may result from the oxidation of acetaminophen to imidogenquinone, while that at 0.27 V is from the reduction of imidogenquinone to acetaminophen. The peak currents on poly(taurine)/MWNT-modified electrodes (d) are much larger than those on (a) a bare, (b) MWNT film-coated, or (c) poly(taurine) film-coated electrode.…”

“…Both titrimetric and spectrophotometric methods involve a tedious extraction process prior to the determination, whereas the LC method is time-consuming. Due to the advantages of low cost, fast response, simple instrumentation, high sensitivity, facile miniaturization, and low power requirement, numerous voltammetric methods of acetaminophen have been developed [31][32][33][34][35][36][37][38][39][40].…”

Selective Electrocatalytic Oxidation of Sorbitol to Fructose and Sorbose

“…The desirable electrochemical properties of TiO 2 nanoparticles can pursue its application for preparation of new modified electrodes with high analytical performances. Previously, TiO 2 nanoparticles based modified electrodes have been applied for the electrochemical analysis of some desired molecules such as glucose 42, 43, ascorbic acid 44, uric acid 45, dopamine 41, levodopa 46, acetaminophen 26, 47, 48, penicillamine 49, adenine 50, guanine 51 and trace colorants in food 52. These investigations have been revealed excellent electrochemical performances such as high sensitivity and good stability of the prepared electrode leading to improved repeatability of the electrode response.…”
