A novel polymer material PEDOT:DBSA was prepared using oxidative polymerization and was modified by cross-linker GOPS and H2SO4-posttreatment. This material exhibits biocompatibility toward cell culture comparable to the glass substrate. The cross-linking process resulted in complete stabilization of PEDOT:DBSA thin film in an aqueous environment, whereas such stabilization was achieved even without high-temperature treatment. The model OECT device proved that the proposed material possesses electrical properties comparable to or even better than other organic mixed conductors used for transistors. This all shows a great potential of PEDOT:DBSA for bioelectronics applications.
