摘要: In this work, a biosensor using glassy carbon electrode modified with gold nanoparticles (AuNPs) and tyrosinase (Tyr) within dihexadecylphosphate film is proposed. Cystamine glutaraldehyde crosslinking agents were used as support for Tyr immobilization. The proposed was characterized by scanning electron microscopy (SEM), transmission (TEM), cyclic voltammetry in the presence of catechol. determination catechol carried out amperometry presented linear concentration range from 2.5×10(-6) to 9.5×10(-5)molL(-1) detection limit 1.7×10(-7)molL(-1). developed showed good repeatability stability. Moreover, novel amperometric method successfully applied natural water samples. results agreement 95% confidence level those obtained official spectrophotometric method.
