We investigate the adsorption of proteins on a partially-charged and end-grafted polyelectrolyte brush using explicit-water and coarse-grained computer simulations and Poisson-Boltzmann theory. The effects of the salt concentration, grafting density, and the charge fraction of the brushes on brush profiles and protein adsorption free energies are calculated and compared to approximative analytical theories.
