Using a combination of ion beam writer and electron microscope, the team carved the symbol of all 118 elements into the strand of hair.
And it wasn't just any hair, it was one plucked from the impressive head of Professor Martyn Poliakoff, an expert in Green Chemistry.
Experts say the etching is so small that a million of the periodic tables could be replicated on a typical post-it note.
Because its Christmas the boffins have also written the message "Merry Christmas" on a snow fragment. Those crazy boffins eh?
Professor Poliakoff said: "Although the application was lighthearted I felt that it enabled us to show people how such nano writing is done.
"Our microscopist, Dr Mike Fay, made the whole operation seem so simple and really demystified it in a most appealing way."
