  • Publication number: 20130017148
    Abstract: Capsules and particles with at least one encapsulated and/or entrapped agent, such as therapeutic agent, imaging agents, and other constituents may be produced by electrohydrodynamic processes. More particularly, the agent encapsulated in a vehicle, capsule, particle, vector, or carrier may maximize treatment and/or imaging of malignant cancers while minimizing the adverse effects of treatment and/or imaging.
    Type: Application
    Filed: September 14, 2012
    Publication date: January 17, 2013
    Inventors: Gustavo LARSEN, Ruben SPRETZ, Raffet VELARDE-ORTIZ, David VU, Luis NUNEZ
  • Patent number: 8308075
    Abstract: To mix immiscible materials at low pressure, the materials are applied from separate inputs of a fixture to separate channels where they are permitted to flow to and spread over surfaces or edges at selected thicknesses. On the surfaces or edges the materials are each subject to flowing air that forms small particles or drops even though the materials may be viscous. The particles or drops are mixed together and may be applied to a combustion device or spray device or any other device utilizing the mixture.

  • Patent number: 8235258
    Abstract: The configuration of a feedstock material is controlled by bringing it into contact with at least a first gas moving against it at a location with an area and thickness of the feedstock liquid that forms drops or fibers of a selected size. In one embodiment, drops of agricultural input materials are formed for spraying on agricultural fields. In another embodiment, nanofibers of materials such as chitosan or metals are formed. In another embodiment seeds are planted with gel. In another embodiment particles carrying desired agricultural inputs with modified release characteristics are delivered.
