Scientists suggest using cavitation to treat cancer

Fighting cancer with nanotechnology
Researchers have determined that cavitation bubbles can occur at much lower pressures than previously thought. This could help develop new cancer treatment technologies and ways to protect industrial structures..
Cavitation is the process of formation and subsequent collapse of bubbles in a liquid stream, which may contain rarefied vapor. Their high temperature shock waves generated during destruction cause erosion of materials, which has a detrimental effect on ship propellers, working elements of pumps, turbines, etc. However, in some cases, cavitation can be beneficial..
Using a national supercomputer, engineers at the University of Edinburgh developed a complex model of the motion of atoms in bubbles and watched them grow in response to small drops in water pressure. It turned out that the critical pressure required for the instability of bubble growth, much lower than predicted by theory.
According to the team, the results of the study could serve as a basis for the development of nanotechnology, which allows using the power of thousands of jets from disintegrating nanobubbles, for example, to treat certain types of cancer or to clean high-precision technical equipment. Scientists also hope this will help limit the detrimental impact on machine performance in the future..
We also previously reported that Russian scientists have found a new way to use silicon nanoparticles to fight cancer.
