AcouTrap

The AcouTrap is a tabletop research platform for acoustic trapping. The central part of the system is an acoustic trapping unit where standing waves are used to trap and hold particles, cells or extracellular vesicles against a fluid flow. The acoustic forces can hold polymer microbeads or cells at sizes down to a few micrometers. For smaller objects, e.g. bacteria, extracellular vesicles or nanoparticles, larger polymer seed particles are initially trapped and smaller objects are drawn to these particles by secondary acoustic forces.

The AcouTrap acoustic cell trapping platform

The AcouTrap platform consists of a motorized stage, syringe pumps and valves to interface the acoustic trapping unit with standard 96 well microplates. The system can aspirate and dispense samples and reagents while keeping your trapped sample immobilized in the trapping unit. After processing the sample, the acoustic forces can be switched off and the sample is dispensed into one of the wells. The system is controlled by a computer through a graphical user interface where it is also possible to create user defined scripts automating the sample handling. PhD Chris Dunning describes how he uses the AcouTrap.
