Abstract
The present invention relates to biodegradable microcapsules based on serum albumin, the preparation thereof and the application thereof to the release of drugs in situ. A feature of the microcapsules according to the present invention is that their wall consists of serum albumin, a portion of which is crosslinked by interfacial polymerization with the aid of an acylating bifunctional reagent, and the other, non-crosslinked portion of which is denatured by means of an alcohol.
