Abstract

Recently, though treatment to inject activated cells to a patient is popular, there’re some side effects and limitation of accumulation efficiency, because the cells spread in bloodstream. Therefore, we have previously reported our attempts for active control of microbubbles (MBs) by using Bjerknes force. In this study, we examined the method to form aggregations including cells (lymphocyte) derived from a rat. After the injection of the MBs and cells, we emitted ultrasound with frequency of 5 MHz and sound pressure of 300 kPa-pp. Figure shows the comparison of aggregations without cells. We estimate cells were included in aggregations, which can be predicted the controllability of cells.
