For optimal performance, biologically active substances such as pharmaceuticals, agrochemicals, and also flavours or fragrances have to be efficiently delivered to their target site and usually released at a well-defined rate. In the case of fragrances the target sites are different types of surfaces from which the active compound then evaporates. Fragrances are very volatile and their perception is therefore limited in time. Furthermore, many of them, ...
