Fig. 1: Sketch of the proposed theoretical framework to determine the electrostatic interactions between inhomogeneously charged particles, where red and blue represent opposite charges.
From: Anisotropic DLVO-like interaction for charge patchiness in colloids and proteins
Detailed formulation is given in Methods and SI. a Essential properties of impermeable internal charge (ICi) and permeable charged shell (CSp) models. b Basic steps in the determination of the pair interaction energies within the two models. c Mapping between the two models achieved by redefining the surface charge distribution of the CSp model so that the surface potential of a single CSp particle matches the one of an ICi particle. d Comparison of the resulting electrostatic pair interaction energies of the potential-matched models.
