Abstract:

BACKGROUND: Several studies have shown that human tissue is closely related to bioelectricity. Therefore, in-depth research on the establishment of cell and tissue electrical microenvironment of materials is a breakthrough for achieving perfect repair and regeneration of defective tissues.
OBJECTIVE: To summarize the application of electroactive biomaterials in tissue engineering.
METHODS: Wiley Online Library, Web of Science, CNKI and Wanfang database were searched to retrieve papers addressing on the research and application of electroactive biomaterials (conductive polymers, piezoelectric materials and carbon-based materials) in tissue engineering published from January 2006 to March 2019. The search terms were "electroactive biomaterials, conductive polymers, piezoelectric materials, carbon-based materials, tissue engineering" in Chinese and “electroactive biomaterials, composite materials, piezoelectric materials, carbon-based materials, tissue engineering” in English.
RESULTS AND CONCLUSION: Electroactive biomaterials possess certain biocompatibility, excellent mechanical properties and signal transmission ability, which can make up for the shortcomings of current biomaterials in regulating cell differentiation and tissue regeneration. So it has a good application prospect in the field of tissue engineering. However, it has some disadvantages such as poor degradation performance and poor mechanical property, which restrict its application. Therefore, it is necessary to fully grasp the characteristics of electroactive biological materials and their advantages and disadvantages, so as to produce the structure and function to the largest extent similar to those of natural tissues, which provide a good electrophysiological microenvironment for cell differentiation and tissue regeneration, and finally intelligently regulate cell differentiation and tissue regeneration.

Key words: electroactive biomaterials, conductive polymers, piezoelectric materials, carbon-based materials, composite materials, tissue engineering, regenerative medicine, scaffold material
