What is it about?
This study explores an exciting new material derived from Navicula sp., a common marine microalga. We've discovered that a special sugar-based molecule, called a sulfated polysaccharide, extracted from these tiny ocean plants can form unique gels when combined with iron. Previously, little was known about how such microalgae polysaccharides behave, especially their ability to gel. We analyzed its components, observed its structure, and found these gels have promising elastic and viscous properties, remaining stable at body temperature. This groundbreaking finding unlocks new possibilities for using sustainable marine resources to create innovative gel-like materials.

Why is it important?
This research offers a sustainable way to create new bio-materials from microalgae, potentially replacing conventional gelling agents. It expands our understanding of marine polysaccharides and their practical applications.
Perspectives
This study paves the way for developing novel materials from abundant microalgae. Our iron-induced gels could be used in biomedical fields, such as surgical anti-adhesion barriers, drug delivery systems, or even in cosmetics and food. Future work will focus on optimizing gel properties and exploring diverse biotechnological applications.
