Ultrasound contrast agents are traditionally used in ultrasound-assisted organ perfusion imaging. Recently the use of coated microbubbles has been proposed for molecular imaging applications where the bubbles are covered with a layer of targeting ligands to bind specifically to their target cells. In this chapter we describe contrast agent microbubble behavior starting from the details of free bubble dynamics leading to a set of equations describing the dynamics of coated microbubbles. Experimentally, the dynamics of ultrasound contrast agent microbubbles is temporally resolved using the ultra-high speed camera Brandaris 128. The influence of a neighboring wall is investigated by combining the Brandaris camera with optical tweezers. It was observed that the presence of the wall can alter the bubble response. A detailed description of the bubble-wall interaction may therefore lead to improved molecular imaging strategies
