Abstract

Here, a novel approach for synthesising calcium oxide (CaO) from seashells was carried out and used as a sensor material for detecting dopamine (DA). The existence of the CaO nanoparticle was confirmed by various characterization techniques like FTIR, UV-visible, and, XRD. The cyclic voltammetry (CV) method was employed for the analysis of DA using a carbon paste electrode (CPE) as the working electrode. The fabricated CaO-modified CPE (CaO/MCPE) was effectively used for the detection of DA using phosphate buffer saline (PBS) as a supporting electrolyte. The sensor exhibited excellent catalytic behavior for the detection of DA in the lower detection range (LLOD= 0.27 μM). Also, the practical application of the sensor was investigated.
