Novel tissue engineering scaffolds fabricated via controlled ice crystallization

By employing 3D scaffolds with both aligned nanofibers and aligned interconnected macrochannels, researchers have taken a nanotechnology-based tissue engineering approach to accelerate the regeneration and repair of damaged tissues at the wound site by directing cells and tissues to grow towards the target site. Their hope is that this leads to the development of affordable and functional biodegradable wound dressings for accelerated healing of chronic skin wounds by promoting regeneration of local tissues.
