An Overview of Polyaniline in Tissue Engineering

Abstract

Electrical response in tissue regeneration has been demonstrate, so growing use of conductive polymers as a main component of scaffolds have developed. Advantages of Polyaniline outweigh other conductive polymers, these including, cost-effective, easy to fabrication, more biocompatible than others, etc. On other hand, cell signaling has been proved as dynamic biochemical that could be promoted cell behaviors such as adhesion, proliferation, and differentiation. In addition, oligoaniline has been emerged to solve some limitation of polyaniline such as biodegradability and biocompatibility problems. Recent researches have been shown that all cells such as cardiac, neural, muscle, bone and fibroblast cells respond to electrical stimulation and to enhance their functions. Bio-mimicking scaffolds is a key role in tissue engineering to achieve a target goal. Hence, the use of polyaniline/oligoaniline has increased. In this review, we investigated properties of polyaniline/oligoaniline and its applications in a variety of tissue engineering.
