Heat-responsive polymers grafted onto gold nanocages serve as a nanoscale delivery system for biologically important compounds. Laser irradiation of the nanocages heats the polymers by means of the photothermal effect; the polymers then change conformation and compounds are released. The polymers return to their original configuration when the laser is switched off, stopping further release.
