Controllable Protein Adsorption and Bacterial Adhesion on Polypyrrole Nanocone Arrays
چکیده انگلیسی

In this research, polypyrrole nanocone arrays doped with β-Naphthalene sulphonic acid (PPy-NSA) were built. This film was expected to control protein adsorption and bacterial adhesion by potential-induced reversibly redox. The scanning Kelvin probe microscopy (SKPM) and surface contact angles (SCA) tests suggested that the surface potential and wettability of PPy-NSA nanocone arrays could be controlled by simply controlling its redox property via applying potential. The controllable surface potential and wettability in return controlled the adsorption of protein and adhesion of bacteria. The proposed material might find application in the preparation of smart biomaterial surfaces that can regulate proteins and bacterial adhesion by a simple potential switching.
