Back Cover: A Hybrid Nanomaterial for the Controlled Generation of Free Radicals and Oxidative Destruction of Hypoxic Cancer Cells (Angew. Chem. Int. Ed. 30/2017)

A hybrid nanosystem for the oxygen-independent generation of free radicals to kill cancer cells under hypoxic conditions is described by Y. Xia et al. in their Communication on page 8801 ff. Gold nanocages filled with a phase-change material are used to deliver a polymerization initiator to generate the free radicals upon irradiation by a near-infrared laser.
