Abstract

The extraction of hydrogel from alginate has garnered significant attention due to its versatile applications in biomedical, pharmaceutical, and environmental fields. Alginate, a naturally occurring polysaccharide derived from brown seaweed, offers a biocompatible, biodegradable, and non-toxic matrix ideal for hydrogel formation. This narrative review explores the various methods for extracting and characterizing alginate-based hydrogels, highlighting the key factors influencing the gelation process, including concentration, pH, ionic strength, and crosslinking agents. By providing an overview of current extraction techniques, material properties, and innovative applications, this review aims to contribute to a deeper understanding of alginate-based hydrogel systems and their potential for future research and development.
