Displacement of particles in microfluidics by laser-generated tandem bubbles.
Abstract
The dynamic interaction between laser-generated tandem bubble and individual polystyrene
particles of 2 and 10 μm in diameter is studied in a microfluidic channel (25 μm height)
by high-speed imaging and particle image velocimetry. The asymmetric collapse of the
tandem bubble produces a pair of microjets and associated long-lasting vortices that
can propel a single particle to a maximum velocity of 1.4 m∕s in 30 μs after the bubble
collapse with a resultant directional displacement up to 60 μm in 150 μs. This method
may be useful for high-throughput cell sorting in microfluidic devices.
