Depletion forces in homogeneous and inhomogeneous binary colloidal mixtures in two dimensions are accounted for by a theoretical approach based on a contraction of the description of liquid mixtures, as well as by computer simulations. We study the depletion interactions in concentrated binary mixtures of additive and non-additive hard discs. The wall-particle depletion potential for a disc close to a hard wall with a concave curvature, or with a relief pattern, is obtained in the infinitely dilute limit, as well as the depletion potentials in mixtures of hard discs and hard plates.
