  A new theory is developed to describe the equilibrium adsorption and
self-assembly of patchy colloids in microchannels. The adsorption theory is
developed in classical density functional theory, with the adsorbed phase and
fluid phase modeled using thermodynamic perturbation theory. In this work we
propose that the introduction of patches on the colloids greatly enhances the
temperature dependent and reversible adsorption of colloids in microchannels.
It is shown how bulk fluid density, patch size, temperature and channel
diameter can be manipulated to achieve the adsorption and self-assembly of
patchy colloids in microchannels.
