An adaptive biointerface from self-assembled functional peptides for tissue engineering

Abstract

A self-assembled peptide-based biointerface is demonstrated with triple functional layers that can significantly improve the tissue self-healing process or prevent biofilm-mediated chronic inflammation. This smart biointerface is composed of three functional moieties (i.e., a cell-adhesive peptide, an infectious environment-responsive peptide, and an antifouling hexaethylene glycol (HEG) layer), and the resulting interface coated onto prosthetic replacements can smartly respond to the surrounding physiological or pathological microenvironment.

Keywords: anti-biofilms; functional peptides; self-assembly; self-healing; tissue engineering.
