  • Nanoparticle entrapment of materials
    Patent number: 8709487
    Abstract: A water-based and surfactant-free microwave synthesis of polymer nanoparticles includes the entrapment of diisopropyl fluorophosphatase (DFPase) within poly(4-vinylpyridine) (PVP) nanoparticles. The resulting nanoparticles are approximately 80-100 nm in diameter and reactive activity of DFPase is maintained after encapsulation.

  • Electrospun nanofibrous membrane assembly for use in capturing chemical and/or biological analytes
    Publication number: 20100240121
    Abstract: A membrane assembly adapted for use in capturing an analyte of interest, the membrane assembly comprising in one embodiment (a) an electrospun nanofibrous membrane, the electrospun nanofibrous membrane comprising a random mat of electrospun nanofibers, at least some of the electrospun nanofibers including one or more types of functional groups; and (b) at least one molecular recognition element immobilized on the random mat via a functional group, the molecular recognition element being adapted to selectively bind the analyte of interest. The membrane assembly may be incorporated into a sensor.

  • Electrospun fibers and an apparatus therefor
    Patent number: 6753454
    Abstract: A novel fiber comprising a substantially homogeneous mixture of a hydrophilic polymer and a polymer which is at least weakly hydrophobic is disclosed. The fiber optionally contains a pH adjusting compound. A method of making the fiber comprises electrospinning fibers of the substantially homogeneous polymer solution. A method of treating a wound or other area of a patient requiring protection from contamination comprises electrospinning the substantially homogeneous polymer solution to form a dressing. An apparatus for electrospinning a wound dressing is discosed.

  • Non-woven elastic microporous membranes
    Publication number: 20020124953
    Abstract: A breathable net-shape microporous membrane structure is created by forming a polymeric solution and electrostatically spinning polymeric fibers from the solution into a microporous membrane structure. The average fiber size ranges from about 0.1 microns to about 1 micron and the average pore size ranges from about 0.4 to about 3.0 microns.
