Evaluation of Alginate Biological Properties

Alginate is a naturally occurring anionic polymer that has been extensively studied due to its biocompatibility, low toxicity, and relatively low cost of use in many biomedical applications. To date, alginate hydrogels have been particularly attractive in wound healing, drug delivery, and tissue engineering applications because these gels retain structural similarity to the extracellular matrix in tissues and can be manipulated to perform several key effects. Furthermore, each alginate production method is unique and requires tuning for its unique properties for practical application. At CD BioSciences, we are working to establish original analytical techniques suitable for evaluating the biological properties of alginate, while fully evaluating the validity of the test method itself. In addition to improving analysis, analytical techniques must be established to properly evaluate materials in the medical field, such as low-endotoxin alginates. To achieve such difficult quality control, advanced analytical techniques with excellent accuracy, reproducibility and specificity for alginate are required.

Alginates Applications in Biomedical Fields

Alginates Applications in Biomedical Fields
  • Pharmaceutical applications
    Conventional roles of alginates in pharmacy include use as thickeners, gel formers, and stabilizers, as alginates can play an important role in controlled release pharmaceutical products.
  • Delivery of small chemical drugs
    Alginate gels are typically nanoporous (with a pore size of about 5 nm), resulting in rapid diffusion of small molecules through the gel.
  • Protein delivery
    Proteins can be incorporated into alginate-based formulations under relatively mild conditions, minimizing their denaturation.
  • Wound dressings
    Alginate dressings minimize bacterial infection of the wound site.
  • Cell culture
    Alginate gels can easily be used as 2-D or more physiologically relevant 3-D culture systems.
