摘要: The transport of water in nanoconfined geometries is different from bulk phase and has tremendous implications nanotechnology biotechnology. Here molecular dynamics used to compute the self-diffusion coefficient D within nanopores, around nanoparticles, carbon nanotubes proteins. For almost 60 cases, found scale linearly with sole parameter θ as D(θ) = D(B)[1+(D(C)/D(B)-1)θ], DB DC totally confined diffusion water, respectively. primarily influenced by geometry represents ratio between total volumes. relationship interpreted thermodynamics supercooled water. As an example, such shown accurately predict relaxometric response contrast agents for magnetic resonance imaging. can help interpreting molecules under conditions tailoring nanostructures precise modulation mobility.
