  • Process for the manufacture of cellulose sulfate with improved characteristics
    Patent number: 8337901
    Abstract: The invention refers to a method for the production of cellulose sulfate which is completely water-soluble and has an adjustable solution viscosity in aqueous solution, which qualifies the produced sodium cellulose sulfate (SCS) as auxiliary material with ideal biological compatibility for biological and medical applications, in particular it is suitable for the encapsulation and immobilization of biological objects, e.g. tissue, cells, microorganisms, enzymes or viruses in microcapsule.

  • Process and apparatus for the production of microcapsules
    Publication number: 20100283166
    Abstract: The present invention relates to an apparatus and a method for producing microcapsules. The apparatus according to the invention comprises at least one bead generator, having at least one nozzle passed by a liquid during operation, with a liquid reservoir arranged before the nozzle. The liquid reservoir comprises a membrane in the region of at least one boundary wall for generating a mechanical oscillation in the liquid. The apparatus comprises at least one reaction and transport device passed by a reaction medium, in which the beads generated in the bead generator are received. Microcapsules are formed during a predetermined reaction time period between at least one first polymeric component of the beads and at least one second polymeric component in the reaction medium and are transported along a reaction path.
