We live in a science fiction world

Dr. McCoy probably had one of these: ‘Pen’ identifies cancer in 10 seconds

The pen is touched on to a suspected cancer and releases a tiny droplet of water.

Chemicals inside the living cells move into the droplet, which is then sucked back up the pen for analysis.

The pen is plugged into a mass spectrometer – a piece of kit that can measure the mass of thousands of chemicals every second.

It produces a chemical fingerprint that tells doctors whether they are looking at healthy tissue or cancer.
