The use of acoustics in microfluidics has become very popular for the past few years because it provides a versatile tool to manipulate small amounts of fluid on a chip in a highly controlled manner. Mixing, pumping, focusing, and deflection have been successfully demonstrated and already included in commercially available products. However, in many cases simple passive techniques, that just exploit a particular flow field and its interaction with soft objects, such as red blood cells, are sufficient to achieve controlled sorting.
In this presentation, we give an overview of existing microfluidics techniques for sorting and manipulation of biological cells and drops used in our lab with special focus on acoustical microfluidics and non-inertial lift force techniques. In particular we show triggered sorting and separation of circulating tumor cells and red blood cells at high speed in microfluidic channels based on laser interrogation similar to FACS (Fluorescence-activated cell sorting).
