Abstract

Abstract : Microfluidic deterministic lateral displacement separates different‐sized particles in slanted pillar arrays. Large particles are displaced by the pillars while smaller particles follow a zigzag trajectory. In article number1701901, Vincent Agache and co‐workers show that intermediate‐sized particles display a different trajectory mode, consisting of successive zigzag and displacement areas. Both experimental results and models are proposed to limit the intermediary mode and optimize the sorting efficiency.
