SENSOR AMPEROMETRICO FOR ANALOGOUS DOPAMINA AND, THE BASE OF IMMOBILIZED CATALYSERS BIOMIMETICOS IN NAFION

NOVELTY – Phenolic compounds detection amperometric sensor has the chloride complex of bis (2,2-dipydl) of copper, (Cu(DiPY)2)Cl2.6H2O1) used as a biomimetic catalyst of Tyr (enzyme tyrosinase) for e.g. dopamine detection. The vitreous carbon electrodes of the sensor are modified by Nafion membrane doped with the catalyst. EMBODIMENT – The sensor response time is 0.5 second. USE – In instrumentation.

Main Application Field
