Regulatory peptides desmopressin and glutathione voltammetric determination on nickel oxide modified electrodes
The determination of important regulatory peptides containing disulphidic bridge and thiols are of much interest. We investigated, via differential pulse voltammetry, the use of glassy carbon electrodes modified with nickel(II) oxide nanoparticles for electrocatalytic oxidation of L-glutathione and desmopressin. Linear response in the range of 0.2 to 6.0 mM of L-glutathione was observed, which brackets …
