A study was conducted to describe methods for performing chemical and electrochemical synthesis of conducting polymers within bioactive aqueous gel matrices formed by peptide amphiphiles (PA). Aqueous PA solutions were allowed to self-assemble in the presence of EDOT monomer, along with the addition of ammonium persulphate, a chemical oxidant that initiates EDOT polymerization. It was observed that the deep midnight-blue color that evolved after the addition served as a visual evidence that polymerization was successful. It was also found that the electrochemical profiles of electrodeposited polymer films derived from the oxidative polymerization of PA-and SDS-encapsulated EDOT were similar.
