Microcapsules are known to be trapped by standing wave of ultrasound in water. Until last year we detected the local change of microcapsules density as brightness variation on echogram. This year we confirmed the same phenomena by optical method. Furthermore, we observed difference of density in microcapsules solution by changing strength of standing wave near bifurcation point of an artificial blood vessel. We have recorded transparent video image of the two lower courses after the bifurcation on microscope and evaluated the brightness average of the two regions in each course. From those results, we confirmed that the density in microcapsules decreases when standing wave is put on the course, where the density increases on the other course. It shows a possibility to control microcapsules direction and to lead to an objective point in blood vessel.
