Abstract
A sensitive and selective electrochemical sensor for detection of dopamine (DOP) using zinc layered hydroxide-sodium dodecyl sulphate-isoprocarb (ZLH-SDS-I)/multiwalled carbon nanotubes (MWCNT) in 100 mM phosphate buffer solution (PBS) and at the pH 8.0 was developed. The morphology and electrochemistry properties of ZLH-SDS-I/MWCNT nanocomposites were characterized using square wave voltammetry (SWV), transmission electron microscopy (TEM), cyclic voltammetry (CV), electrochemical impedence spectroscopy (EIS) and scanning electron microscopy (SEM). Under optimized conditions, the linear analytical curve for determination of dopamine was 1.0 µM to 0.3 mM with the detection limit of 0.43 µM. Besides that, the proposed sensor also exhibited good selectivity, stability, sensitivity and was found to be applicable for dopamine detection in the commercial dopamine hydrochloride injection samples
