A general theoretical model for particle deposition and transport in heterogeneous porous media is developed. The model can describe the transient particle deposition and the nonuniform particle coverage of porous media surfaces, resulting from surface charge heterogeneity, surface roughness, or oth

✦ Synopsis
Magnetically driven self‐assembly of colloidal particles into highly ordered structures on a substrate is demonstrated. This process allows for programming of specific geometrical patterns of colloidal particles. It also permits assembly of well‐defined colloidal patterns of many different particle types, possibly carrying different labels, e.g., fluorescently labeled beads (see Figure), or different molecular species.

## Abstract Particles combining multiple anisotropy dimensions offer possibilities for self‐assembly that have not been extensively explored to date. The scope for assembly of microparticles in which the anisotropy dimensions of internal bond angle and chemical ordering have been varied is investig
