Abstract
A microfluidic chip assembly having a plurality of microfluidic flow channels is provided. Each channel has a switching region. The microfluidic chip may further include at least one surface acoustic wave generator configured to generate a pressure pulse in the switching regions of the channels to selectively deflect particles in the flow. Attenuation elements and/or channel configurations may be used to prevent acoustic signals from interfering with neighboring switching regions. Alternatively, a microfluidic particle processing system may include a microfluidic chip assembly, a particle processing instrument, and a coupling element. The surface acoustic wave generator may be provided on the particle processing instrument. The microfluidic chip assembly may be configured for operative engagement, via the coupling element, with the particle processing instrument. The coupling element may transmit acoustic energy from the surface acoustic wave generator to the switching regions and/or to focusing regions of the flow channels.
