A Review on : Nanogels

Abstract

Nanogels are defined as nanoscale particles that are assembled utilising networks of physically or chemically cross-linked polymers that expand in a suitable solvent. Hydrophilic three-dimensional networks make up nanogels. These investigations take into account characteristics for topical drug delivery because of their comparatively high drug-encapsulation ability, uniformity, ease of production, negligible toxicity, and stability in the presence of serum, including stimuli responsiveness. These may be loaded instantly into aqueous media because they are water-soluble. These are produced utilising a wide range of procedures, such as the photolithographic method, membrane emulsification, and polymerization methods. Because nanoparticles are trapped in the gel matrix when nanogels are employed as dermatological preparations, they have longer contact periods with the skin and, as a result, have longer therapeutic potencies.
