Patent number: 7431986Abstract: A stabilized emulsion is employed to produce shelf stable, controlled release, discrete, solid particles or pellets which contain an encapsulated and/or embedded component, such as a readily oxidizable component, such as omega-3 fatty acids. An oil encapsulant component which contains an active, sensitive encapsulant, dissolved and/or dispersed in an oil is admixed with an aqueous component and a film-forming component to form an emulsion.

Publication number: 20080176792Abstract: The present invention concerns novel methods of identifying peptide sequences that selectively bind to targets. In alternative embodiments, targets may comprise cells or clumps of cells, particles attached to chemicals compounds, molecules or aggregates, or parasites. In preferred embodiments, target cells are sorted before exposure to the phage library. The general method, Biopanning and Rapid Analysis of Selective Interactive Ligands (BRASIL) provides for rapid and efficient separation of phage that bind to targets, while preserving unbound phage. BRASIL may be used in preselection procedure to subtract phage that bind non-specifically to a first target before exposing the subtracted library to a second target. Certain embodiments concern targeting peptides identified by BRASIL and methods of use of such peptides for targeted delivery of therapeutic agents or imaging agents or diagnosis or treatment of diseases.Type: ApplicationFiled: August 24, 2007Publication date: July 24, 2008Inventors: Wadih Arap, Renata Pasqualini, Ricardo J.

Publication number: 20080152815Abstract: A self-healing coating, incorporating medium-sized microcapsules filled with a liquid formulation, repairs itself upon physical compromise. In one embodiment, a commercial primer is mixed with these microcapsules and applied. After the coating has cured, any physical compromise of the cured coating results in the microcapsules bursting to release the liquid, in turn filling and sealing the compromised volume of the coating. In applications where a product is used to provide corrosion protection, the liquid contains anti-corrosion material as well as suitable diluents and film-forming compounds. In a preferred embodiment, the microcapsules are provided separately to be mixed with commercial products during preparation for application of the coating. For example, if a paint formulation is known a priori, tailored microcapsules packaged separately from the paint and designed for use with the paint formulation, are wet mixed into the paint during preparation for application.Type: ApplicationFiled: February 22, 2007Publication date: June 26, 2008Inventors: Larry D. Stephenson, Curtis Thies, Ashok Kumar, Srinivasan Sarangapani

Patent number: 7375140Abstract: A process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner is provided wherein a dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel in such a manner that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by the shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.Type: GrantFiled: November 28, 2005Date of Patent: May 20, 2008Assignee: Japan Science and Technology AgencyInventors: Toshiro Higuchi, Toru Torii, Takashi Nishisako, Tomohiro Taniguchi
