Industry Award Sarastro wins industry award for controlled-release technology

| Redakteur: Kathrin Schäfer

In recognition of its APE encapsulation technology for the controlled long-term release of active substances in disinfection applications, Saarland-based Sarastro GmbH received this year’s industry award from publishers Huber Verlag für Neue Medien in the category Medical Technology.

The APE principle goes beyond previous encapsulation technologies in which active substances can be released only through external intervention, such as the application of pressure or addition of acid. Sarastro has developed a technology involving encapsulating and protecting the active substances so that they are released only at the desired site in a controlled fashion and over an individually adjustable period.

Targeted release of active substances

This controlled-release technology can be applied in the form of coatings or in volume delivery; in the latter case, the active substance is introduced as a master batch directly into a medical device’s material of construction for release from the device surface.

Sarastro’s technological know-how lies in the manufacture of a highly porous sponge structures consisting of agglomerated inorganic nanoparticles. Pore size or surface characteristics of the sponge material control the speed at which the active substance is released from the agglomerate. In production, the manufacturer adjusts the pore size and polarity of the nanomaterial so that aromatic and active substances are released in the correct quantity for the application over the desired time period. Nanoparticulate systems for this purpose are commercially available.

Toward serial manufacture

The technology is already used for disinfection in industrial settings. Also, Sarastro manufactures a fresh-scented disinfectant permitted for hospital use. Its germ-killing effect, thanks to APE technology, is proven to last for 10 days. Efforts to begin series production of intelligently functionalised plastics such as polyethylene, polypropylene, polycarbonate and PET for medical technology, pharmaceutical packaging and other applications are now under way.
