Sažetak
Charge reversal as an extreme case of charge compensation is directly observed by capillary electrophoresis for a negatively charged peptide in aqueous solutions of trivalent cations. Atomistic and coarse-grained simulations provide molecular interpretation of this eff ect showing that it is largely of electrostatic origin with a minor contribution of chemical speci ficity of the salt ions.
