Tiny spinning molecules which can drill into cancer cells and kill them in just 60 seconds have been developed by scientists.

The nanomachines move according to light and they are able to make their way through cell linings because of their speed, according to The Telegraph.

In order for the nanomachines to move an ultraviolet trigger has to be used, or else they just sit on the cell surface and cause no damage.

A test was completed at Durham University which found that nanomachines were able to break through the outer lining of a prostate cancer cell in one to three minutes and this killed the cell immediately.

Dr Robert Pal said: "We are moving towards realising our ambition to be able to use light-activated nanomachines to target cancer cells such as those in breast tumours and skin melanomas, including those that are resistant to existing chemotherapy.

“Once developed, this approach could provide a potential step change in non-invasive cancer treatment and greatly improve survival rates and patient welfare globally."

In order to work the nanomachines have to spin at two to three million times per second, else they won't have the momentum to get past obstacles.

It is thought that these molecules could not only kill the cells but could also bring therapeutic agents to them.

Researchers are currently conducting experiments on microorganisms and fish, but are hoping to start tests on rodents soon before starting human clinical trials if the research proves successful.
