Ultrasound-actuated microfluidic flow focusing allows control of bubble size and production rate

Sarah Cleve, Tim Segers, Michel Versluis, Guillaume Lajoinie

Microfluidic flow focusing is a promising tool for the creation of monodisperse microbubbles, such as ultrasound contrast agents. However, industrial-scale bubble production remains elusive due to a lack of control over bubble size and production rate in devices with paralellized flow-focusing…
