- Abstract:
- A new concept of hybrid nano-biosensors was developed based on well-defined methacrylic diblock copolymers and metal nanoparticles (Au and Pd). The nano-composite systems were used as surfactant for modified carbon electrodes. The electrochemical characterization (Potentiostat/Galvanostat method) was performed by using reference redox molecules in order to test the sensors sensitivity and reproducibility at different concentrations of dopamine in acid medium (0.1 M HCl). It was shown that the functionalization of carbon electrodes with well-defined electrically active diblock copolymers and metal nanoparticles offer superior metrological performance for neurotransmitters analyze, comparing to conventional electrodes.
