  • Patent number: 9801820
    Abstract: A composite particle including a core with at least one carrier material; a fluidizing material layer on the surface of the core; and an outer layer comprising nanoparticles of an ingestible material distributed in at least one matrix-forming material. A process of making the composite particles includes the steps of dry coating carrier particles with a fluidizing material; preparing a suspension of nanoparticles of an ingestible material distributed in a matrix-forming material; and fluid bed coating the carrier particles with the suspension. The process and products provide quick dissolving composite particles which can be used for delivery of poorly water soluble ingestible materials in suitable dosage forms. The process of the invention reduces or prevents particle agglomeration during fabrication of the composite particles to enable delivery and quick redispersion of nanoparticles of the ingestible material from a dosage form.

  • Publication number: 20120220198
    Abstract: A method of producing from particles of a layered material platelets comprising the layered material, the method comprising the steps of: mixing the particles of the layered material in a liquid medium; and exposing said mixed-in particles to a mechanical grinding treatment, thereby exfoliating at least some of the particles of the layered material to produce platelets from the layered material. Moreover, a method of producing from particles of a layered material platelets comprising the layered material, wherein the particles are exposed to a mechanical grinding treatment using grinding media, the stress energy of the grinding media SEGM being smaller than 10 ?Nm.
