Review on hydrogels – its topical application for wound healing action

Abstract

In the area of wound healing, the need for treating broad and deep untreatable wounds is growing with each day. Wide, deformed, deep, or massive wounds are unable to repair by our cell system or tissue repair mechanism, resulting in dysfunction and deformity. Furthermore, the dressings or medications often used relieve pain result in slow healing, scarring, and sometimes even death. As a result, hydrogel is used to repair and seal the loss component as a 3D polymeric matrix with a broad range of properties for soft, sensitive to hard and tough tissue or organ. There are several sophisticated, smart, and intelligent hydrogels that are made up of natural and synthetic polymers and are developed for proper encapsulation and regulated release of drugs or biomolecules under key biological circumstances. As a result, the hydrogel is being used amongst the most effective matrices for tissue regeneration and drug testing. In this article, we address the polymer used to make hydrogels, as well as methods for evaluating hydrogel wound dressings to help direct the development of new hydrogels.
