How drilling into cells could kill off cancer

TiNy machines that rotate have been developed to drill into and kill diseased cells, or deliver medication precisely where it’s needed.

The nano-machines are so small that 50,000 could fit across the diameter of a human hair.

The motor is made of a chain of atoms that begins to spin when activated by light. in a joint enterprise between durham and North Carolina universities in the u. S., the nanomachines were found to be able to drill through prostate cancer cells in the lab. They were also able to deliver a coloured dye within a cell.

A single device can penetrate a cell’s membrane in around a minute, reports the journal Nature.
