In development Application 2: Biocompatible Polymers

Features and Properties

  1. Has excellent blood compatibility.
    Platelet inactive, Complement inactive, Nonhemolytic
    Does not coagulate blood over a long period of time, even without the additional use of anticoagulants.
  2. Inhibits the adsorption of proteins.
  3. Inhibits the adsorption of microorganisms.
  4. Cell adhesion can be controlled by selecting the composition.
    It is also possible to have both antithrombogenicity and (tissue) cellular adhesiveness.

Examples of Applications

  • Coating agents for medical equipment
  • Water-insoluble pharmaceutical solubilizing agents
  • Drug delivery system (DDS)
  • Cell culture base materials
  • Cell tissue scaffolding materials
  • Cancer diagnosis kits
  • Adhesion prevention agents

Excellent Antithrombogenicity

Inhibits and does not activate platelet adhesion.

Inhibition of Protein Adsorption

1. Inhibits the adsorption of blood-derived proteins.
2. Inhibits adsorption in various proteins with differing surface charges.

Inhibition of Microorganism Adhesion

Inhibits the adhesion of pathogens in various applications (water treatment, oral cavity, medical and health care applications, etc.).

Control of Cellular Adhesiveness

Selecting the composition changes cellular adhesiveness, making it possible to control culture behavior.
Two-to-three-dimensional culture and suspension culture are possible for various cells.
It is also possible to have both antithrombogenicity and (tissue) cellular adhesiveness.
Endothelial cells and fibroblasts can be engrafted and propagated while maintaining antithrombogenicity.
