How multiple interpenetrating polymer molecules behave in a confined space is a problem of interest both from a biological and a technological standpoint. We probe a solution of DNA molecules confined in a slit-like geometry on a nanofluidics chip. Inside the nanoscale slit, the DNA molecules are compressed via hydrodynamic flow against a barrier permeable only to solvent; the resulting compressed DNA solution concentration profile is recorded as a function of position in the slit. We develop a theoretical model for this concentration profile based on mean-field assumptions and using the Onsager Variational Principle. We find that this model yields a nonlinear Schrödinger type equation governing the concentration profile. We fit this model ...
