An intra-droplet particle switch for droplet microfluidics using bulk acoustic waves
To transfer cell- and bead-assays into droplet-based platforms typically requires the use of complex microfluidic circuits, which calls for methods to switch the direction of the encapsulated particles. We present a microfluidic chip where the combination of acoustic manipulation at two different harmonics and a trident-shaped dropletsplitter enables direction-switching of microbeads and yeast cel
