  • Patent number: 9682203
    Abstract: The invention relates to a depot for storing and dispensing a substance into a gas phase, having a hybrid structure made of an open-pored macroporous support skeleton, through which a gas can flow, and nanoporous particles immobilized on the support skeleton, which in the pores thereof contain at least one active ingredient to be released, wherein the support skeleton consists of particles or fibers that are permanently connected to each other.

  • Patent number: 7939103
    Abstract: A process for the production of CS particles (10) and microcapsules (12) is described, in which at least one active compound (4) is adsorbed in porous templates (2) (A), as a result of which templates (5) filled with active compounds are present. Subsequently, the templates (2) are provided (B) with a primer layer (6) which is intended to facilitate the subsequent construction of the capsule shell (9). The capsule shell is formed (C) by applying alternately charged polyelectrolyte layers (8). Filled CS particles (10) are obtained. By subsequent dissolution of the templates (2) the active compounds (4) are released (D) from the template into the interior of the microcapsules. The active compounds (4) remain enclosed there or are slowly released (E) from the capsule.

  • Publication number: 20090304756
    Abstract: The invention relates to the filling of hydrophobic or hydrophobically modified porous microparticles with hydrophobic substances with subsequent encapsulation of the resulting hydrophobic particles using layer-by-layer (LbL) polyelectrolyte technology for the purpose of preparing homogeneous suspensions in water, and also for the controlled release of the encapsulated active ingredients. Through a specific modification of the LbL surface it is possible to realize preferred adhesion at the target site.

  • Publication number: 20060141148
    Abstract: The invention relates to a gradual coating method (LBL-technology®) with poloyelectrolytes of microparticles and nanoparticles in aqueous gels and gelatinous media, whereby regularly occurring flocculation and coagulation problems,which arise as a result of high collision frequency (Brownian movement and/or hydrodynamic collision) amongst the particles to be coated and as a result of heterocoagulation with the coating material, can be avoided. The coating compositions are conveyed to the particles which are to be coated by diffusion or by means of external forces of an electric, magnetic, dielectrophoretic and hydrodynamic variety. According to the invention, the coated cores can be disintegrated or dispersed after coating while maintaining the integrity of the multi-layered shell. The coating products and/or the empty coating shells can be obtained once the gel has been broken and can be further processed.
