Pig Skin Isn’t Just for Footballs Anymore

Believe it or not, but researchers have made pig-skin lasers.

The technology outlined in a paper published in Nature Photonics, showed that pumping light into fat cells could turn them into tiny, self-contained lasers. The microlaser technique could afford scientists new ways to study and use cells.

The team at Harvard University turning cells into lasers has tried it before.

This time the team showed that some cells could lase on their own. They chose pig fat because each cell contains a large, nearly perfectly spherical ball of fat inside it.

It’s just not pig fat lasers.

The team also found they could turn other cells into a laser by injecting oil droplets into them. They also tried inserting tiny polystyrene beads to change the turning of the laser.

By combining beads of different sizes with several fluorescent dyes, the researchers estimated they should be able to create roughly as many unique laser tags as there are cells in the human body.
