Abstract
Electrochemical deposition of gold nanoparticles (AuNPs) and l-cysteine on glassy carbon electrode was carried out to prepare a
modified electrode. The fabricated sensor showed good sensitivity and selectivity for simultaneous determination of paracetamol and
tramadol by square wave voltammetry. Linear ranges of 0.10-10.7 μM (paracetamol) and 0.50-63.6 μM (tramadol) were obtained with
detection limits of 0.03 and 0.17 μM, respectively. The proposed electrode was used successfully in the simultaneous determination of the
drugs in spiked human plasma samples.
