Recent Applications of Natural Polymers in the Formulation of Nanogel

Abstract

Abstract: Nanotechnology is a progressing and novel technique in healthcare and smart drug delivery. There are many benefits and future aspects of nanogel-containing nanoparticles in the advanced diagnosis, mitigation, and treatment of many important disorders with improved outcomes because of their particle size, high stability, biodegradability, biocompatibility, large surface area, and high drug charging capacity. Their small particle size provides the feature basis for drug charging capacity and the swelling property to form a 3D structure with advantages, limitations, and classification of nanogels. The motive of the review article is to summarize the natural polymers such as Okra gum, chitosan, Acacia gum, Pullulan, PLA, and PLGA that are employed to prepare nanogels comprising nanoparticles by the chemical cross-linking method. There are various applications of these nanogels as nanoparticles in the many fields of healthcare, including local anesthetics, neurodegenerative, vaccine delivery, transdermal delivery, ophthalmology, and diabetes. In this present review article, the author has focused on the current trends of nanogel in nanomedicine, oilfield applications, food packing, cancer research, cosmeceutical, and biomedical applications.
