Characterization of HGFK1 Signaling Networks in Microvessel Endothelial and Hepatoma Cell Lines

Laser generated ultrasound (LGU) is now established as an important non contact technique. The use of pulsed lasers for LGU by direct illumination of a sample surface is a well documented method [1–6]. Aside from the comparatively low repetition rates of lasers suitable for LGU, a factor that limits their use is surface damage may be caused. LGU usually occurs between two extreme regimes, the ‘ablative’ regime (intense longitudinal waves generated at the expense of surface damage) and the ‘thermoelastic’ regime (damage free but relatively inefficient source for normal incidence waves)
