High-speed droplet generation on demand driven by pulse laser-induced cavitation

摘要

We report on a pulse laser-driven droplet generation (PLDG) mechanism that enables on-demand droplet generation at rates up to 10,000 droplets/sec in a single-layer PDMS-based microfluidic device. Injected droplet volumes can be continuously tuned between 1 pL to 150 pL with less than 1% volume variation.
