  • Patent number: 9504761
    Abstract: A stabilized chitosan-based nanoparticle is provided having a chitosan polymer and a hydrophilic dispersing agent. In the stabilized nanoparticle, chains of the chitosan polymer electrostatically interact with chains of the hydrophilic dispersing agent to form an entangled network between the chitosan polymer and the hydrophilic dispersing agent. The stabilized chitosan-based nanoparticle has optimal particle integrity and stability properties under physiological conditions.
    Type: Grant

  • Publication number: 20110021745
    Abstract: A method of making ultra-small chitosan nanoparticles having a size range of approximately 10-20 nm, includes preparing a first microemulsion containing effective amounts of cyclohexane, n-hexanol, chitosan polymer and a nonionic surfactant. A second microemulsion is prepared containing effective amounts of cyclohexane, n-hexanol, tartaric acid, EDC, n-hydroxysuccinimide, and a nonionic surfactant. The method continues by reacting the first and second microemulsions for a time sufficient to form the ultra-small chitosan nanoparticles and recovering the nanoparticles from the reacted microemulsion. The chitosan polymer may be crosslinked and may also be tagged with a fluorescent compound, a radio-opaque compound, a paramagnetic ion, a ligand specific for a predetermined biologic target, a drug, and combinations thereof.
