Abstract
A nanostructure was prepared from titania nanoparticles and copper oxide (TiO2NP@CuO) and used to modify a carbon paste electrode (CPE). The modified CPE is shown to enable sensitive voltammetric determination of the drug clozapine (CLZ). The sensor was characterized by various techniques and some key parameters were optimized. Under the optimum conditions and at a working potential of 0.6 V (vs. Ag/AgCl), the modified CPE has two linear response ranges, one from 30 pmol L-1 to 4 nmol L-1 of CLZ, the other from 4 nmol L-1 to 10 mu mol L-1. The detection limit is as low as 9 pM. The transfer coefficient (alpha) and catalytic rate constant (k(cat)) were calculated and the reliability of the sensor was estimated for CLZ sensing in real samples where it gave satisfactory results.
