Abstract

The combination of microarray and microparticle technologies can result in synergistic effects for high-performance bioassays. Here, we present a porous microwell platform that is used to generate large-scale, ordered microparticle arrays. We guide particles to the microwells via hydrodynamic forces associated with fluid flow through open pores inside the microwell. After particles block the microwell perfectly, applied pressure deforms the microparticles to squeeze into the slightly smaller microwells. With this process, we demonstrated large-scale (10<sup>3</sup>-10<sup>4</sup>) particle assembly with high filling yield (94 %) and high assembling of initial particles (88 %). Sorting was based on size, modulus, and shape (specificity > 95 %).
