Ultrapure Alginates: Properties and Applications in the Biomedical Field


Alginate is a natural polysaccharide extracted from brown seaweed. Its non-animal sourcing, biocompatibility, and availability in ultrapure form make it ideal for biomedical applications. Alginate can be crosslinked with divalent ions to produce hydrogels with tunable mechanical properties. It is composed of 1,4 linked β-D-mannuronate (M) and α-L-guluronate (G) – monomers that control its gelling behavior

This presentation will first provide an overview of ultrapure alginates produced by IFF NovaMatrix®. It will highlight the unique molecular properties of alginates including options to functionalize and create various gel morphologies. We will discuss specific studies showcasing the potential uses of alginates and their hydrogels in key biomedical applications, specifically cell-based immunotherapy and 3D bioprinting.

Key takeaways:

  • Alginates' fundamental properties and tunable gelation behavior.
  • Potential modifications to alginates and how functionalization expands their areas of use.
  • Recent literature data showing use of alginates in cell-based immunotherapy and 3D bioprinting.
