| abstract |
A delivery system for an active substance, comprising a substrate on which the substance is loaded for subsequent release,wherein: (i) the substrate has been at least partially coated with a polymer using plasma deposition (preferably pulsed plasma deposition); (ii) the active substance is present as a guest molecule within a cyclodextrin inclusion complex; and (iii)the inclusion complex is bound to the polymer through a chemical linkage formed between a hydroxyl group on the cyclodextrin and a functional group on the polymer. The system may be used to control the release of an active substance such as a perfume. Also provided are methodsfor preparing (a) the delivery system and (b) a functionalised substrate for use as part of the system, in which the polymer is suitably reacted with a cyclodextrin using an S N 2 nucleophilic substitution reaction, in particular a Williamson ether synthesis reaction. |
