Abstract: Nanogels are three-dimensional networks at the nanoscale level that can be fabricated through physical
or chemical processes using polymers. These nanoparticles’ biocompatibility, notable stability, efficacious
drug-loading capacity, and ligand-binding proficiency make them highly suitable for employment as drug-delivery
vehicles. In addition, they exhibit the ability to react to both endogenous and exogenous stimuli, which
may include factors such as temperature, illumination, pH levels, and a diverse range of other factors. This facilitates
the consistent administration of the drug to the intended site. Alginate biopolymers have been utilized
to encapsulate anticancer drugs due to their biocompatible nature, hydrophilic properties, and cost-effectiveness.
The efficacy of alginate nano gel-based systems in cancer treatment has been demonstrated through multiple
studies that endorse their progress toward clinical implementation. This paper comprehensively reviews
alginate and its associated systems in drug delivery systems.
