Simultaneous voltammetric determination of antihypertensive drugs nifedipine and atenolol utilizing MgO nanoplatelet modified screen-printed electrodes in pharmaceuticals and human fluids

Simultaneous determination of nifedipine and atenolol in combined dosage forms using a boron-doped diamond electrode with differential pulse voltammetry

“…28 In addition, Table 3 also presents the comparison of the analytical parameters of the here-reported method with those obtained to MgO-NPLs/SPE. 21 In this case, BDDE presents a lower LOD value for ATN. Most electrodes used in the individual determination require a large preparation time, complexity in its preparations, and avoiding mercury due to its toxicity.…”

“…[9][10][11][12][13][14][15][16] BDDE is widely used due to significant properties such as a good electrochemical stability in alkaline and acid media, lower residual current, and wide working potential range, which makes it possible to determine compounds with high oxidation potentials without interference of water decomposition and inertness of the surface to adsorption of reaction products. [17][18][19][20] There is one voltammetric method described in the literature for the simultaneous voltammetric determination of NIF and ATN, 21 underscoring the importance of this work for publication. Recently, Khairy et al 21 development a MgO nanoplatelets modified screen printed electrode (MgO-NPLs/SPE) for the simultaneous voltammetric determination of both of these antihypertensives in pharmaceutical tablets and human urine samples.…”

Several voltammetric individual determinations of ATN have been proposed using different electrodes such as BDDE, 22 carbon paste electrode modified with mordenite type zeolite (MOR/CPE), 23 glassy carbon electrode modified with gold nanoparticles/multiwall carbon nanotubes (AuNPs/MWCNTs/GCE), 24 and GCE modified with C 60 (C 60 /GCE).…”

Large-scale production of CdO/Cd(OH)2 nanocomposites for non-enzyme sensing and supercapacitor applications

“…These electrodes have been used extensively in previous studies. 5,8,[25][26][27] Here, rst, a carbon-graphite ink formulation (product code C2000802P2; Gwent Electronic Materials Ltd, UK) was screen-printed onto a polyester (Autostat, 250 mm thickness) exible lm (denoted throughout as standard-SPE). This layer was cured in a fan oven at 60 C for 30 min.…”

“…Connectors for the efficient connection of the screen-printed electrochemical sensors were purchased from Kanichi Research Services Ltd (UK). [25][26][27][28]…”
