The dopamine, an important neurotransmitter, in abnormal concentration can be associated with the appearance of some neurological diseases. Based on the necessity of dopamine control, we propose a fast and more straightforward ...

Bioelectrodes were developed based on a simple deposition of graphene oxide (GO) or reduced graphed oxide (rGO) and laccase (Lac) on a glassy carbon (GC) electrode surface. The morphology and electrochemical behavior of ...

In this work nanostructured film composites of the monoamine oxidase B (MAO-B) enzyme, free or encapsulated in liposomes, were fabricated by the layer-by-layer (LbL) self-assembly technique, employing polyethylene imine ...

Dopamine (DA) is a neurotransmitter with multiple functions in the central nervous system, and whether found in low levels, activation of biological defense system and physiological activity is influenced. DA at abnormal ...

The electrocatalysis of dopamine has been studied using a cobalt hexacyanoferrate film (CoHCFe)-modified glassy carbon electrode. Using a rotating disk CoHCFe-modified electrode, the reaction rate constant for dopamine was ...

Pyrolytic graphite electrodes (PGE) were modified into dopamine solutions using phosphate buffer solutions, pH 10 and 6.5, as supporting electrolyte. The modification process involved a previous anodization of the working ...
