  • Biologic modulations with nanoparticles
    Publication number: 20040038303
    Abstract: Certain aspects of the invention relate to the use of small particles in biological systems, including the delivery of biologically active agents to cells or tissues using nanoparticles of less than about 200 nm in approximate diameter. Embodiments include collection of particles having a bioactive component, a surfactant molecule, a biocompatible polymer, and a cell recognition component, wherein the cell recognition component has a binding affinity for a cell recognition target. Compositions and methods of use are also set forth.

  • Nanoparticle encapsulation system and method
    Patent number: 6632671
    Abstract: The present invention generally relates to nanocapsules and methods of preparing these nanocapsules. The present invention includes a method of forming a surfactant micelle and dispersing the surfactant micelle into an aqueous composition having a hydrophilic polymer to form a stabilized dispersion of surfactant micelles. The method further includes mechanically forming droplets of the stabilized dispersion of surfactant micelles, precipitating the hydrophilic polymer to form precipitated nanocapsules, incubating the nanocapsules to reduce a diameter of the nanocapsules, and filtering or centrifuging the nanocapsules.
    Type: Grant
