Nano-Machines Kill All Cancers

Scientists have created light-driven spinning nanomachines that could killĀ cancerĀ cells in just 60 seconds.

In laboratory tests, researchers showed how the molecules can be activated by ultraviolet light to spin up to three million times a second and drill through cell membranes.

In one test, it took between one and three minutes to cut through the outer shell of prostate cancer cell and destroy it.

Another application for the tiny ‘nanomachines’ might be to deliver therapeutic medicines, researchers say.

A sequence of images taken over 10 minutes shows a human prostate cell under attack by motorized molecules. The cell, tagged with a green fluorescent protein, is made permeable by the nanomachines, which drill through its lipid bilayer membranes. The right images clearly show blebbing (bubbling) of the membrane as cytoplasm leaks out of the cell
