Magnetic iron oxide maghemite (Fe2O3) nanoparticles with covalent surface-bound CO-releasing molecules can be triggered to release CO through heating in an alternating magnetic field. In the present proof-of-concept study, conjointly performed by researchers from the Univerity of Düsseldorf and the Ernst Ruska-Centre in Jülich, the rate of CO-release from [RuCl(CO3)-(l-DOPA)] nanoparticles was fournd to be doubled upon exposure to an external alternating magnetic field (31.7 kAm1, 247 kHz, 25 8C, 39.9 mTesla, DOPA = dioxyphenyl-alaninato). The study made extensive use of the high-resolution tranmission electron mircosopce of the ER-C allowing to investigate the atomic structure of ligand shell nanoparticles at atomic resolution.
