Polydopamine (PDA) film coatings are multifunctional substances because these coatings can adhere to nearly all known solid materials. The self-polymerization of dopamine in aqueous solution was investigated in this study; PDA films are an effective platform for further functionalization similar to the reduction of silver ions into silver nanoparticles (NPs). The films provide a new method to attach metal NPs on substrates. Through this simple method, glucose sensors based on this kind of Ag NPs/ITO exhibited a detection limit of about 10 μM and presented a good sensitivity enough for real use (3-8 mM).
