Claim Text:
1. A method of preparing a suspension of microbubbles for use in a carrier liquid, wherein the microbubbles have a gas core and a liquid shell, said liquid shell comprising magnetic nanoparticles, and wherein the method comprises the steps of: (a) determining a size of the shell relative to the gas core and an amount of the nanoparticles in the shell of a microbubble that satisfy the following conditions: (b) using the amount of nanoparticles in the shell and the relative size of the shell to the gas core of the microbubble to determine the amount of the magnetic nanoparticles and the amount of liquid for the shell needed to prepare a suspension of the microbubbles; and (c) preparing a suspension of the microbubbles using the amount of the magnetic nanoparticles and the amount of liquid for the shell needed to prepare the suspension.
