Abstract: [Display omitted] • Trans -(Cl,Cl)-[Ru(FT)Cl 2 (NO)](PF 6) nanoparticles (free of surfactants or carrier matrices) were successfully grown in water. • This simple synthetic route allowed to control the size of the nano-objets. • Nanoparticles were NO donors upon irradiation at 365 nm. We described the facile preparation of nanoparticles of a photoactivable ruthenium nitrosyl complex. Nanoparticle sizes were investigated by atomic force microscopy and nanoparticle tracking analysis. For nanoparticles dispersed in water, nitric oxide (NO) photorelease was evidenced at 365 nm. The quantum yield of photorelease was found to be of about 0.04. Electron paramagnetic resonance as well as measurements by a NO sensor confirmed NO release upon photolysis of nanoparticles. This work showed that these nanoparticles allowed a spatiotemporal control of NO release upon light irradiation and are potential NO nanoplatforms for biological applications. [ABSTRACT FROM AUTHOR]
