Abstract(in English) | Microcapsules are known to be acted force from ultrasound. Making use of the phenomena that microcapsules of μm order collapse themselves after ultrasound emission near their resonant frequency, physical DDS (Drug Delivery System) has been proposed. We have detected the local change of microcapsules density by producing standing wave near the bifurcated point in the artificial blood vessel. Then we estimated theoretically condition for active path selection of capsules at the bifurcated point. Furthermore, we observed difference of density in capsules suspension by changing strength of acoustic radiation force near the bifurcated point. Comparing the experimental results with theoretical equations, the condition for active path selection is calculated from acoustic radiation force and fluid resistance of capsules. It showed a possibility to control capsules direction and to lead to an objective point in blood vessel. |
