The concept is based on the interaction of resonant semiconductor iron oxide Fe2O3 nanoparticles with light. Particles previously loaded with the antitumor drug are injected in vivo and further accumulate at the tumor areas. In order to release the drug non-invasively, the carrier particles have to be light-sensitive. For this purpose, the polymer containers (capsules) can be modified with iron oxide resonant semiconductor nanoparticles. When irradiated with light, they get heated and induce drug release.

Exceptional advances in the control of material properties has been achieved, through careful manipulation of geometry on nano- and sub-nanometre length scales, in magnetoelectronics and nanomagnetism.1 Advanced techniques now allow for the creation of structures patterned on sub-micron length scales in three dimensions. New phenomena has been discovered in patterned magnets that can be strongly controlled by ion bombardment, multilayering, and lithographic patterning.
