Abstract

Method for releasing a material in a controlled manner from amphiphilic compounds. The material to be released is enclosed inside a membrane formed of an amphiphilic compound, in which or inside which membrane noble-metal nanoparticles are incorporated. Light of a sufficiently strong intensity is directed to the amphiphilic compounds for a sufficiently long time for the membrane to change phase, as a result of the increase in temperature, and to open an exit path for the material.
