Abstract

In this paper, a micro/nano-nozzle driven by cavitation bubble-induced jetting flow is proposed and demonstrated. A microfluidic chip with a micro-nozzle is designed and fabricated. A cavitation bubble created using a pulsed laser system close to the boundary of the micro-nozzle. Since the effect of the solid boundary, a jetting flow is introduced by the asymmetrical collapse of the bubble and the testing microbeads are projected by the jet through the connection channel between fluid chamber. The mean velocity of the jet is up to 1.2 m/s. This technique is easy to be integrated to other nano/microfluidic system and it has great potential in single cell analysis and high throughput cell sorting.
