Now nanotechnologies are one of perspective methods of diagnostics in medical practice. Nanoparticles can be used as contrast agents for medical ultrasonic introscopy due to their adhesion to tumor cells and bacteria. The mathematical model of the laser excitation of acoustic signals in a liquid medium with the presence of the nanotubes was developed and numerically studied. Increasing of the level of photo acoustic signal was shown.
