We present an efficient sonochemical microreactor system based on micromachined surfaces which generate microbubbles in a liquid when exposed to an ultrasonic field. Cavitation of these bubbles leads to radical formation, introducing chemical reactions in the solution. The system exhibits a high sonochemical yield at conditions which would otherwise not produce any significant chemical effect, ...
