Electrosynthesis and characterisation of poly(folic acid) films

The obtained films were characterised microscopically and electrochemically applying atomic force microscopy (AFM) and electrochemical methods such as cyclic voltammetry (CV), square wave voltammetry (SWV) and electrochemical impedance spectroscopy (EIS) in different media. The best film was obtained when PFA was electrosynthesised from 0.1 mol L−1 KCl/HCl solution, pH 2.0, covered with G-Chit composite film. The best electrochemical behaviour of such electrode was in the same buffer solution. This electrode will be further applied to (bio)sensor construction.
