摘要: Abstract In this study, an enzymatic electrochemical biosensor for l -lactate detection was proposed. The device developed based on gold nanoparticles (Au NPs) modified zinc oxide nanorods (ZnO NRs). sensing performance of the examined by cyclic voltammetry and amperometry. Compared with pristine ZnO biosensor, Au/ZnO sensor exhibited higher sensitivity 24.56 μA cm−2 mM−1, smaller K M app 1.58 mM, lower limit 6 μM wider linear range 10 μM–0.6 mM detection. introduction Au NPs enhances electro-catalytic ability electron migration, which contributes to improvement performance. Hence, results confirm essential character in such semiconductor biosensing system.
