Polymers pushing Polymers: Polymer Mixtures in Thermodynamic Equilibrium with a Pore [PDF]

Biophysical Journal, 2012
We investigate polymer partitioning from polymer mixtures into nanometer size cavities by formulating an equation of state for a binary polymer mixture assuming that only one (smaller) of the two polymer components can penetrate the cavity.
