Chitosan 99% represents ultra-high purity chitosan with a Degree of Deacetylation (DAC or DDA) of >99%.

Applications

1. Advanced Gene & Nucleic Acid Delivery

• Serves as an efficient non-viral vector for mRNA, siRNA, and plasmid DNA encapsulation. The high positive charge density condenses nucleic acids into stable polyplex nanoparticles for cell transfection.

2. Tissue Engineering & Regenerative Medicine

• Formulated into ultra-pure bio-inks for 3D bioprinting, nerve guidance conduits, and cartilage matrices where trace acetylated impurities could trigger undesirable immune responses.

3. Hemostatic & Surgical Biomaterials

• Used in high-grade emergency hemostatic sponges, vascular plugs, and internal surgical sealants where immediate, rapid platelet aggregation is required.

4. Precision Drug Delivery Systems

• Creates pH-sensitive mucoadhesive nanoparticles for targeted oral, nasal, or ophthalmic drug delivery with minimal cytotoxicity.
