Near-wall hindered diffusion: Implications for surface-based sensors

Abstract:

Brownian motion of nanoscale analytes near interfaces is a crucial requirement for the development of numerous surface-based sensors, especially for the detection of individual freely diffusing particles such as enzymes, proteins, viruses, or nanoparticles. The modelling of diffusion processes near surfaces is much complicated by the hydrodynamic effect of near-wall hindered diffusion of unbound particles at liquid-solid interfaces resulting in anisotropic diffusion at the boundary. We model ...
