Simultaneous voltammetric determination of glutathione, doxorubicin and tyrosine based on the electrocatalytic effect of a nickel(II) complex and of Pt:Co nanoparticles as a conductive mediator

The Determination of Timolol Maleate Using Silver/Tannic Acid/Titanium Oxide Nanocomposite as an Electrochemical Sensor in Real Samples

“…Several methods, such as highperformance liquid chromatography (HPLC) [6][7][8], ultraviolet-visible spectroscopy (UV-Vis) [9,10], and electrochemical sensors [11,12], have been proposed to determine TM. The electrochemical techniques are essential to determine drugs and other ingredients present in pharmaceutical drug formulation, and the determination of electrode mechanisms is another use of electrochemistry [13][14][15][16].…”

A new nickel-based co-crystal complex electrocatalyst amplified by NiO dope Pt nanostructure hybrid; a highly sensitive approach for determination of cysteamine in the presence of serotonin

“…Selecting a suitable catalyst with high selectivity is one of the most important steps in the design of electrocatalytic sensors 42 – 46 . According to previous reports, inorganic complexes, especially complexes with nickel central atom can be used as a suitable electrocatalyst in the analysis of important pharmaceutical and biological constituents 47 – 52 . Although nanomaterials such as carbon nanotubes and graphene with high-conductivity have been proposed for the preparation of electrochemical sensors, their high cost, hard synthesis methods, and high capacitive charging current are some of the most important criteria for their use in electrochemical sensors 53 – 61 .…”
