Programmable Assembly of Heterogeneous Colloidal Particle Arrays

Abstract

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.
