  • Microencapsulation of pancreatic islets within a thin coat of glucagon-like peptide-1 functionalized poly(ethylene glycol)
    Publication number: 20070190036
    Abstract: Microencapsulation of pancreatic islets within a thin poly(ethylene glycol) (PEG) coat is provided. The PEG coat is functionalized with an insulinotropic agent, glucagon-like peptide 1 (GLP-1). The encapsulated pancreatic islets may be used for the treatment of type I diabetes.

  • Microencapsulation of particles in a polymer solution by selective withdrawal through a high viscosity low density fluid and subsequent crosslinking
    Publication number: 20070009668
    Abstract: The invention provides methods and apparatus for encapsulating particles. An inverted selective withdrawal technique is employed. Two immiscible fluids are added to a container, a first fluid is an aqueous pre-polymer solution with a crosslinking reagent and a second fluid is denser highly viscous fluid. A selective withdrawal tube pulls particles suspended in the first fluid through the second fluid. The particles retain a thin coating of the first fluid. The coated particles are then subjected to a crosslinking process where the pre-polymer solution of the first fluid surrounding the particles is converted into a hydrogel capsule.
