Recent advancements in sodium alginate-based nanogels

Nanogels are widely recognized as a comprehensive hydrophilic framework for encapsulating foreign molecules. They can respond to environmental stimuli and can be utilized for a variety of purposes. Despite their evident benefits, nanogels are not yet widely used in medical care. Herein, we have attempted to emphasize some of the significant obstacles that must be addressed to improve nanogels in biological applications. The purpose of this chapter is to discuss the characteristics and process of formation of sodium alginate (NaAlg)-based nanogels. Owing to their easy customizing capabilities and the capacity to successfully encapsulate various treatments, nanogels are being investigated as drug delivery agents for cancer. Nanogels are efficiently ingested by target cells and do not accumulate in nontarget tissues, resulting in reduced treatment dosages and fewer detrimental adverse effects. This chapter briefly discusses N-isopropylacrylamide-, curcumin-, keratin-, aminopropyltrimethoxysilane-, and chitosan-based NaAlg-based nanogels.
