Electrochemical detection of Flutamide as an anticancer drug with gold nanoparticles modified glassy carbon electrode in the presence of prostate cancer cells

Abstract

In the current study, a novel electrochemical sensor was constructed based on gold nanoparticles modified glassy carbon electrode (AuNPs/GCE) to detect Flutamide. Field emission scanning electron microscope was used to identify the morphology of the modified electrode. Cyclic voltammetry and differential pulse voltammetry (DPV) were used to investigate the electrochemical activity of the modified electrode. Flutamide concentration, pH, and scan rate were optimized as electrochemical parameters. Flutamide peak currents obtained by DPV were linear within the concentration range of 1–600 µM, and the detection limit was calculated as 1.5 nM. In addition, the fabricated electrochemical sensor was successfully employed to detect Flutamide in a cell culture media containing prostate cancer cells as the biological sample. The stability of the modified electrode within a day showed an appropriate precision.
