  • ORAL DRUG DELIVERY DEVICE WITH EXPANDING BAND
    Publication number: 20230355532
    Abstract: The present disclosure provides a drug delivery device. The drug delivery device is taken orally by a patient, and a capsule degrades within the gastrointestinal (GI) tract of the patient. An expanding band coated with a drug and located within the capsule expands and interfaces with the interior of the GI tract, allowing the drug to diffuse through the GI tract. After a period of time, the expanding band degrades and passes through the GI tract.

  • METHODS FOR PRODUCING NANOPARTICLES AND USING SAME
    Publication number: 20170087530
    Abstract: A method for producing nanocomposite particles is provided. The method comprises supplying an organic phase fluid an organic phase fluid, an aqueous phase fluid, an amphiphile, and a plurality of hydrophobic nanospecies to a nozzle. An electric field is generated proximate the nozzle such that the fluid exiting the nozzle forms a cone jet that disperses into a plurality of droplets. The plurality of droplets are collected, and nanocomposite particles comprising a self-assembled structure encapsulating at least one hydrophobic nanospecies form by self-assembly.
