| Abstract(in English) | Acoustic cavitation, the primary mechanism of sonochemical effects, is known to be much more difficult to induce with progressive waves than with standing waves. We recently found that acoustic cavitation can easily be induced even by progressive waves when the second harmonic is superimposed on the fundamental. The synergy between the fundamental (0.5 MHz) and the second harmonic (1 MHz) on inducing in vitro sonochemical reaction and sub harmonic emission was demonstrated. The intensity threshold for forming a focal lesion through cavitation in mouse liver tissue was also significantly lowered by second-harmonic superimposition, especially with an administration of a sonochemically active porphyrin. |
