Light-sensitive implantable devices for "on demand“ drug release

The system consists of a biocompatible film or patch containing a dispersion of gold nanoparticles, which act like light transducers, producing heat upon light stimulation, and of thermosensitive nanosponges, which serve as a reservoir for the drug molecules to be released. The temperature rise generated by the nanoparticles triggers a contraction in proximal nanosponges, thus promoting the expulsion of the drug to the external environment in a very controllable and localized way. The patches can be applied either on the skin or inside the body with high levels of safety and comfort.

The use of these devices may assist in performing advanced and personalized pharmacological therapies, in which the release of precise drug amounts to specific body regions is required.
