Abstract We report a straightforward and reproducible electrochemical approach to develop polydopamine-ethanolamine (ePDA-ETA) films be used as immunosensing interfaces. ETA is strongly attached polydopamine during the potentiodynamic electropolymerization of dopamine. The great advantage methods generate oxidized species (quinones), which can readily react with amine groups present in solution, subsequent incorporation this molecule polymer. presence its effect on electrosynthesis was...
The facile deposition of polydopamine on virtually any material and its recognized adhesive properties justify extensive application in the biomedical field. However, these films are heterogeneous, poorly conductive impermeable to many small molecules ions, limiting their use electrochemical applications. Hereby, we have potentiodynamically grown gold using an anodic potential limit 1.1 V, higher than typically used values (0.5−0.8 V), aiming at preparing thick permeable films. mass...
