Alginate

Alginates extracted from brown seaweed can be used to make bioproducts for a range of applications from single-use packaging to tissue engineering. To scale alginate production for widespread use, a focus on advancing sustainable extraction methods is needed. This study aimed to investigate greener extraction methods and the effect on alginate properties, to advance sustainable methods suitable for bioplastic applications. Three alginate extraction protocols were selected by evaluating the hazard levels of different alginate extraction methods, solvents and reagents.

Mesenchymal stem cell (MSC) treatments are promising for cellular therapy and tissue regeneration for their abilities to self-renew and differentiate. Treatments require billions of MSCs, but current production methods using proteolytic enzyme detachment have issues with cell detachment and premature differentiation. MSC health and quantity (detachment efficiency) can be improved by using dissolvable bioactive modified-alginate films instead.
