The purpose of this study is to develop a new ultrasonic contrast agent for the drug delivery system (DDS). Ferromagnetic materials or magnetic carbons were placed on the surfaces of the surfactant microbubbles developed in our laboratory for the above purpose. Multivalent ions such as calcium ions were used to place the ferromagnetic materials or magnetic carbons on the surfaces of the microbubbles. It was confirmed that the developed magnetic microbubbles could be lead by a permanent magnet. Furthermore, the performance of the magnetic microbubbles was evaluated by measuring the time dependence of the attenuation constant as one of their acoustic properties.
