| Abstract(in English) | We have ever proposed a physical DDS (Drug Delivery System) by making use of the microbubbles of inn order, which have a possibility to contain the specified drug and also are easily affected under ultrasound emission near their resonant frequency. Also the feature to use the bubbles is easily detected and actuated by ultrasound. However, because of the diffusion of bubbles after injection inside human body, it was difficult to enhance the efficiency of medication in the disease part. So we tried to trap the fluid bubbles by using local acoustic radiation force. We have observed that the bubbles were trapped in an artificial blood vessel, to evaluate the effect of acoustic radiation force. The trapped area of bubbles was increased according to amplitude, emission time of ultrasound and was decreased according to frequency. From those results, we derived optimal conditions to trap the bubbles. |
