Vibrating microbubbles poking individual cells: drug transfer into cells via sonoporation.

Ultrasound contrast microbubbles have the ability to enhance endothelial cell permeability and thus may be used as a new way to deliver drugs. It facilitates the transfer of extracellular molecules into cells activated through ultrasound driven microbubbles. The present study is designed to correlate the relationship between microbubble induced cell deformation and enhanced cell membrane permeability.
