Abstract
Self-reinforced tissue shields are useful as ophthalmic shields, wound dressings, wound barriers, nerve repair, therapeutic drug delivery devices and the like. The self-reinforced tissue protective shields comprise gelatin, chitosan and reinforce and are made by a method comprising forming inter-molecular locking within a solution through electrostatic forces, eliminating the use of extra cross-linking methods, the solution mainly comprising natural existing polymers that are biodegradable and biocompatible.
