The electrochemical behavior of these substances is influenced by various factors, including: intermetallic compounds formation, diffusional effects or electrostatic effects, depending on the type of change that takes place on the electrode surface. %K dopamine %K glucose %K tyrosinase %K glucose oxidase %K laponite %K microgel %K enzyme biosensor %U http://www.saber.ula.ve/bitstream/123456789/31053/5/artic1.pdf
