â¢Fabrication of NiO/CNTs and new catechol derivative modified carbon paste electrodeâ¢Good ability of proposed sensor for biological and pharmaceutical analysisâ¢Simultaneous determination captopril, acetaminophen, tyrosine and hydrochlorothiazide
A novel nanomaterial-based voltammetric sensor has been developed for use a highly sensitive tool for the simultaneous determination of captopril (CA), acetaminophen (AC), tyrosine (TY) and hydrochlorothiazide (HCTZ). The device is based on the application of NiO/CNTs and (2-(3,4-dihydroxyphenethyl)isoindoline-1,3-dione) (DPID) to modify carbon paste electrodes. The NiO/CNTs nanocomposite was synthesized through a direct chemical precipitation approach and was characterized with X-ray powder diffraction (XRD), and scanning electron microscopy (SEM). The NiO/CNTs/DPID/CPEs were found to facilitate the analysis of CA, AC, TY and HCTZ in the concentration ranges of 0.07-200.0, 0.8-550.0, 5.0-750.0 and 10.0-600.0 μM with the respective detection limits of 9.0 nM, 0.3 μM, 1.0 μM and 5.0 μM. The developed NiO/CNTs/DPID/CPEs were used for the determination of the mentioned analytes in pharmaceutical and biological real samples.
Graphical abstractIn this study a novel sensor based on NiO/CNTs and (2-(3,4-dihydroxyphenethyl)isoindoline-1,3-dione) (DPID) modified carbon paste electrode fabricated for simultaneous determination of captopril, acetaminophen, tyrosine and hydrochlorothiazide for the first time.Download high-res image (93KB)Download full-size image
