We attempt a microrobotic drug delivery system (DDS) in which drug carriers of air-filled microcapsules are recognized with echography and are controlled using resonant ultrasound. We have confirmed the physical possibility of resonance design for drug carriers depending on the shell structure of the microcapsule. In addition, we have developed a novel echographic imaging system to locate microrobots precisely. Path lines of microrobots in blood flow could be clearly visualized.
