چکیده انگلیسی
Gold nanoparticles (AuNPs) were electrodeposited onto a glassy carbon (GC) electrode to increase the sensitivity of the tyrosinase (TYR) electrode. By controlling the applied potential and time, the coverage of AuNPs at the TYR electrode was optimized with respect to the current response. The voltammetric measurements revealed a sensitive enzymatic oxidation and electrochemical reduction of substrate (phenol and catechol). The quantitative relationships between the inhibition percentage and the pesticide concentration in various water samples were measured at the TYR-AuNP-GC electrode, showing an enhanced performance attributed by the use of AuNPs.
