Abstract

We present a novel fabrication method for the creation of sub-100 micron 3D-shaped particles. Recently, we reported a 3D shaped particle generation method termed optofluidic fabrication [1, 2]. While the approach allows for an infinite set of 3D particle shapes by changing pillar and light pattern configurations, the approach is limited to mm-scale particles and lacks system tunability due to fixed channel geometries, not easily allowing for diverse shapes. Here, we overcome these two limitations by introducing a channel with a cross-section reduction and with on-the-fly pillar fabrication via UV polymerization to successfully create sub-100 micron 3D microparticles.
