Abstract:- Nanogels are nano-sized particles which are composed of hydrogel. These are crosslink network of hydrophilic polymers. Most of nanogels are synthesized by using synthetic polymers or biopolymers which are physically as well as chemically crosslinked. Due to presence of hydrophilic functional group nanogel can hold more amount of water. Generally particles present in nanogels are of 10 to 200 nanometers. Nowadays nanogels are widely used for the drug delivery. Nanogel has fascinated significant attention as one of the most flexible drug delivery systems mainly for targeted drug delivery and prolonged drug delivery of bioactive agents due to their integrate characteristic of hydrogel and nanoparticle. This review focus to provide a perception into the different roles that nanogels can play for enhance tissue regeneration, for decreasing frequent doses and increase the possibility of effective pharmacological action. Nanogels have an intensity of drug loading capacity and it exhibit better permeation capabilities due to smaller size. They can be administered by several routes such as oral, nasal, parenteral, pulmonary, intra-ocular etc. Nanogels can be used for the treatment of cancer, diabetes, bone regeneration and inflammation. They are the novel drug delivery systems for both hydrophilic as well as hydrophobic drugs.
