Our group is investigating the influence of acoustic waves on squamous cell carcinoma cells of the head-neck area in order to to determine their mechanical properties. A piezoelectric actuator with a sharp tip is used to produce sound waves in the range from 0,5 to 10 kHz. A detailed characterization of the acoustics is necessary for a better understanding of the interaction between the sound waves and the cells.
Temperature measurements at different distances in direction of oscillation and additional as a function of time have been performed in order to determine the temperature-profile in the vicinity of the probe. Additionally, the output energy was characterized. The experimental setup and the probe’s characteristics will be presented in detail.
Furthemore, we observed the behaviour of the cancer cells on acustic waves at various frequencies and sound intensities. These results will be presented as well.
