Abstract

The present invention relates to a method of producing and loading silk particles, preferably spider silk particles, with a compound. In particular, the present invention provides a novel two step method for loading silk particles, preferably spider silk particles, with small and water-soluble compounds. Also disclosed are silk particles, preferably spider silk particles, loaded with at least one compound which are eminently suited as carriers for controlled and sustained delivery applications. Furthermore, the invention relates to pharmaceutical or cosmetic compositions comprising said silk particles, preferably spider silk particles, and a pharmaceutically active compound or cosmetic compound for controlled and sustained release. The present invention is also directed to silk particles, preferably spider silk particles, loaded with a compound obtainable by the method according to the invention.
