Nanoparticle transport models in confined fluids

摘要

Nanoparticle (NP) transport in confined fluidic structures has applications in areas of energy, nano manufacturing and biomedical industries. NP diffusion under nanoscale confinement was studied using mesoscale particle dynamics with interactions determined by colloidal physics. We find that at this scale, subtle changes in the geometry of confinement produces changes in energy barrier that results in changes of diffusion transport mechanism and NP penetration into nanoconfined structures. The results were correlated with continuum methods to determine effective diffusivities of fluids that accommodate the NP interactions. Our models will contribute towards better understanding of phenomena for optimizing NP transport in drug delivery systems and other nanoscale devices.
