Does water suffer from claustrophobia? The local structural and dynamic properties of water in confined (300–4000 nm) spaces were characterized by an NMR study of the size-dependent relaxation phenomena, which in turn reflect changes in water mobility and proton transfer. The results are important for understanding fluidics in extended nanospaces and in implementing micro-/nanofluidic devices.
