According to an article in today’s Daily Telegraph in the UK, Google has recently filed a patent application for a wrist-wearable device that could be used to destroy specific proteins or even cancer cells.
In the patent application, Google states that certain proteins have been implicated as a partial cause of Parkinson’s disease; that their wearable device could be used to destroy these proteins; and that the destruction of such proteins might thus slow the development of the disease.
The patent application continues by stating that
As a further example, the target could be cancer cells; by selectively targeting and then modifying or destroying the cancer cells, the spread of cancer may be diminished.
It is already widely understood that Google has been investing in cancer research through its Google X research company. In October 2014 it became public that Google X was developing a pill capable of detecting cancer and other diseases.
