Abstract

Here, we propose a universal technique to firmly capture dispersed microparticles on any desired two-dimensional array of through-pores on a surface. The 10 μm silica or polystyrene particles are reversibly captured, making them accessible for direct manipulation and inspection or subsequent transfer to other surfaces. To obtain perfect arrays with a pitch of 1.25 μm, perforated devices with profiled surfaces were required. Additionally, the method has proven successful for both types of particles, either dispersed in water or ethanol. The assembly technique may serve as a platform for manufacturing hierarchical materials, e.g., ordered chromatography packings, or performing cellular assays.
