RESUMO
Nanogels are cross-linked, nano-sized hydrogels with dimensions ranging from 20 to 200 nm. Nanogel-based nanoplatforms have proven to be an excellent choice for pharmaceutical formulations. Nanosystems have properties that are very useful in polymeric drug delivery applications, and their particular strength is that they have these nanosystemic properties and can thus merge with polymeric materials. Drug-carrier size is designed to be nano-sized in order to maintain optimal stability, resulting in more surface area and interior space. This also allows for a prolonged period of time for loaded pharmaceuticals to circulate. They can be classified by stimuli responsive or non-responsive behavior and type of linkages present in the network chains of gel structure. Nanogel can be synthesized by Photolithographic, modified pullulan, emulsion polymerization reverse microemulsion polymerization inverse miniemulsion polymerization and free radical crosslinking polymerization technique. Hybrid nanogels are different from conventional polymer nanoparticles often employed for drug administration. They can encapsulate bioactive medicines and regulate the release of such medications over time and in particular areas. The hybrid nanogels used to create a specific form of the hybrid, especially one geared towards increasing targeted drug delivery, enhance the effectiveness of ailment treatments, but perhaps the introduction of a multifunctional nanogel-based drug delivery system.
