Abstract
A system for sequential exposure of particles to different fluid streams includes an acoustic actuator device for acoustically driving one or more substrates and a microchannel device of the one or more substrates that receive particles in a first flowing fluid, moves the particles to a second flowing fluid, then moves the particles out of the second flowing fluid using acoustic radiation generated by the acoustic actuator device. The system can control residence times in the streams. According to one use, the first flowing fluid is a cell buffer and the second flowing media is an electroporation buffer. An electroporation system is placed in or downstream of the acoustic actuator device. However, in other uses, the second flowing media might be a wash buffer.
