We work on developing polymeric biomaterials to facilitate nerve regeneration. One of our research topics is to bridge transected peripheral nerve across a critical gap by nerve guidance channels or so called nerve conduits. Nerve conduits are fabricated from biodegradable polymers with novel structural designs of aligning microgrooves and asymmetric microporosity. The microgrooved/microporous conduits serve as a delivery vehicle for neurotrophic factors or/and cells. After the efficacy of the nerve conduits was evaluated in rats, rabbits, and pigs, we transferred the associated technology to industry. We also design injectable self-healing hydrogel for the treatment of brain injury and stroke. Through these research efforts, we seek to develop new biomaterials and answer some fundamental biological questions for example regarding the proper milieu including the extracellular environment for nerve regeneration. Our main interest is to use materials technology to deliver therapeutic agents (growth factors/genes/cells) to dysfunctional tissue as well as to combine all of these technologies to develop possible new therapeutics for nerve repair. We are seeking serious collaborators in the hope that the associated medical products mentioned above may be realized in the future.
