Sessile drop experiment

In this short video we see a field of sessile drops, many of them in the 50 to 100 micron range, mimicking the mass of many types of human cell. The sound used to excite the drops is code 133 of Cyma Technologies AMI 1000 sound therapy device. The entire field is around 4mm in width yet the uptake of acoustic energy is significantly different between the various sizes of microscopic sessile drops, and at the point of Faraday Instability only two droplets reach full expression, while in others there is a very reduced acoustic uptake. This suggests that resonance may play a major role in the ability of cells to absorb acoustic energy.
