What is it about?

Natural compounds have been obtained from ocean with a variety of applications in biomedical and biotechnology fields. These natural compounds serve as a renewable source for biomedical applications. A positive impact has been found in device fabrication with its suitable system development. Marine polysaccharides that originate from the ocean have low extraction cost, interact strongly with other biocompounds, and are soluble in aqueous solvents and extraction media.

Why is it important?

Marine polysaccharides are extracted from algae such as carrageenan, alginate, and fucoidan. Hyaluronan and chitosan are obtained from animal sources. Biocompatibility, biodegradability, antimicrobial action, adhesive action, and antiinflammatory activity are common properties of marine polysaccharides.


Owing to these properties, marine polysaccharides are used in drug delivery devices, capsules, particles, and hydrogels. Controlled release of therapeutic agents is achieved by using marine polysaccharides in regenerative medicine and gene delivery, to fight against serious diseases.
