Technology Need

Developing responsive biomaterials is a key to tissue engineering for tissue repair and regeneration. An environmentally benign biodegradable polymer will break through the bottleneck of conductive polymers in biomedicine which will broaden their applications in on demand drug release, tissue regeneration and biodegradable electronics. Existing biodegradable conductive materials are multi component systems which require adding inorganic additives or dopants. Apart from being highly complex, these additives/dopants cause risks of toxicity and complications in-vivo, which limit their broad bio-medical application. However, none of the existing biodegradable polymers are conductive without dopants/addictive. 

Invention Description/Solution

UTA researchers have developed a novel conductive polymer that conducts by itself without additives or dopants. The novel polymer addresses major challenges such as instability, uncontrollability, and complexity that plaque the existing conductive materials. The novel polymer is formed by chemically integrating biodegradable segment, doping molecule and conductive segment into single polymer chain. The synthesized polymer is conductive without dopants, soft, and elastic with good cell compatibility. Besides biomedical application, the novel polymer opens a new avenue for biodegradable electronics and also traditional chemical and electronics industry.
