“Organic Bioelectronic Interfaces Based on PEDOT:PSS-Based Crystal line Films, Microfibers, and Fibrillar Hydrogel”
In t his research, we developed organic bioelectronic interfaces based on highly crystalline poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT: PSS) films or microfibers to overcome the trade-off between electrical/elec trochemical performance and aqueous stability. Crystalline PEDOT:PSS films exhibits excellent electrical/electrochemical/optical characteristics, long -term aqueous stability without film dissolution/delamination, and good via bility for primarily cultured cardiomyocytes and neurons over several weeks . Furthermore, they are successfully employed for PEDOT:PSS-based multi-ele ctrode arrays (MEAs) to record and stimulate the activities of primarily cu ltured cardiomyocytes and chicken retinae tissues. In parallel, we develope d crystalline PEDOT:PSS microfibers for single-strand wearable electrochemi cal transistors, PEDOT:PSS-incorporated hydrogel microfibers for 3-D neuron al network reconstruct, and metal oxide transistor arrays for transparent d irect cellular interfaces.
