Hydrogels: A review

Abstract

Hydrogels are hydrophilic, three dimensional and polymers network that
hold the large quantity of water of biological fluids. Water is the large
constituents of human body which applied for the biomedical purposes.
Polymers are playing significance role in the pharmaceutical field.
Hydrogels are biomaterials due to their important quantities such as
biocompatibility, biodegradability and non toxic properties and these
properties makes hydrogel acceptable for medical and pharmaceutical
field. This article concerning the general knowledge about hydrogels i.e.
significance, method of preparation, synthesis of hydrogels, chemical
and physical properties, feature, advantage and disadvantage.
