Photofunctional multilayer films by assembling naked silver nanoparticles and a tailored nitric oxide photodispenser at water/air interface

► Nanostructured hybrid films of silver nanoparticles (AgNPs) and a tailored nitric oxide (NO) photodonor. ► Strong interactions between the two components at the air/water interface. ► Presence of both isolated AgNPs and nanoassemblies of AgNPs in the films. ► Release of NO exclusively controlled by visible light stimuli. ► Intriguing bimodal systems for biomedical research studies.
