An extensive review on hydrogel: Its classification and biomedical application

Abstract

This review focuses on the brief introduction of hydrogels that are highly swellable system and have the capacity to absorb large amount of solvent and increase much more in size as compared to their original size. The review comprises of the different types of hydrogels and specifically focuses on the application of the hydrogels in biomedical filed. Hydrogels have the tendency to release the chemical or therapeutic moiety that is loaded inside them through different mechanism. A number of stimuli-based responses of hydrogels have been observed. All of these characteristics make hydrogels a promising system in the field of drug delivery and other biomedical applications.
