Nano-gels: A versatile nano -carrier platform for drug delivery systems: A mini review

摘要

Nowadays the application of nanotechnology in different biomedical fields such as drug delivery is increasing due to its unique advantages. With this in mind, it is widely believed that nanogels as the nanometer-sized networked polymeric particles have a considerable impact on drug delivery systems as biocompatible nanocarriers due to their unique characteristics such as high loading capacity, sustainability and so on. The nanogels have the three-dimensional constructions containing the hydrophilic or hydrophilic polymeric chains that they can physically or chemically absorb a large amount of water without their dissolving within water so that polymer structure is reversible as well as the capability of swelling. These nanomaterials are made using polymeric precursors and heterogeneous polymerization monomers, and recently some researchers have reported the networked nanogels based on optical processes. In this review, we will try to address methods to synthesize the nanogels as well as study their applications as drug delivery systems with examples of pharmaceutical systems.
