Abstract

We aimed to create autonomous on-chip systems that perform targeted translocations of nano- or microscale particles in parallel using machinery that mimics biological systems. By exploiting biomolecular-motor-based motility and DNA hybridization, we demonstrate that single-stranded DNA-labeled microtubules gliding on kinesin-coated surfaces acted as cargo translocators and that single-stranded DNA-labeled cargoes were loaded/unloaded onto/from gliding microtubules at micropatterned loading/unloading sites specified by DNA base sequences. Our results will help to create autonomous molecular sorters and sensors.
