Abstract
Co3O4-NiO nanocomposites at different molar ratios have been prepared using a simple sol–gel me-thod. The composite were used as electrode materials for detecting L-tyrosine, modifying a screen printed electrode (SPCE). The electrochemical sensor response to L-Tyrosine (concentration-Tyr) in PBS pH=7.4 and at [0μM–100μM] has been investigated by using cyclic voltammetry (CV).Results obtained demonstrated that the composite Co3O4-NiO/SPCE sensors exhibit good electroanalytical performances, with a maximum of sensitivity exibited at a Co3O4:NiO ratio = 1.
