A Comprehensive Review on Hydrogels

Abstract

The conventional drug delivery systems have a long list of repeated dosing and toxicity issues. The hydrogels solve these issues as they minimize such activities and optimize therapeutic benefits. The hydrogels possess tunable properties that can withstand degradation, metabolism, and control release moieties. Some areas of applications of hydrogels involve wound healing, ocular systems, vaginal gels, scaffolds for tissue and bone engineering, etc. They comprise about 90% of the water that makes them suitable bio-mimic moiety. Here, we present an extensive review of various perspectives of hydrogels, along with their applications.

Keywords: Hydrogels; cross-linking; scaffolds; targeted drug delivery; vaginal gels; wound healing.
