A team of researchers at the California Institute of technology proposed a new and radical method of destroying cancerous cells via low-intensity ultrasonic waves.
Prior to that, the greatest efficiency in the fight against cancer cells showed a method of using high intensity focused ultrasound (HIFU). Under its influence, the affected cancerous tissue is heated and killed. The main problem of HIFU is that it is not possible to precisely focus the flow of these waves at affected tissue, resulting in can suffer healthy tissue.
Became breakthrough 2016, when researchers at the California Institute of technology Mike Ortiz and Stephanie Hayden published an article in the journal of the Mechanics and Physics of Solids, in which he announced the creation of a mathematical model showing the dramatic difference between the frequencies of resonance in healthy and cancer cells.
In theory this means that a very finely tuned sound wave, the vibration stimulating nucleolar membrane of a cancer cell, will gradually bring it to break point. The natural frequency gap between healthy and malignant cells should leave healthy cells intact.
It should be clarified that this research is in its earliest stages. This method was tested only on cell cultures, it must now continue on solid tumors, then on animals and then on humans.
