  • Inhaler system for volatile substances
    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.

  • Method for the Encapsulation and Controlled Release of Poorly Water-Soluble (Hyprophobic) Liquid and Solid Active Ingredients
    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.
