University Logo Tattoo on Human Hair: a Micro-Scale Rebellion?

Illustration for article titled University Logo Tattoo on Human Hair: a Micro-Scale Rebellion?

What do you do if you have a focus ion beam microscope normally used to make nano-devices, a scanning electron microscope and some spare time? Well, you etch your university logo onto a human hair, of course! At least, if you're the Engineering Dept at McMaster University you do. It's not the smallest logo ever— that's an IBM one with 35 xenon atoms, I believe. But it's possibly the ickiest, and it's certainly high resolution. Impressive. We've only got one quibble: the uni logo, guys? I'm sure Giz readers would be more imaginative.


Now, this is done on a plucked hair by steering a beam of gallium ions over the surface to etch the 20-micron logo into the hair cells. But imagine you really could have your hair tattooed. No-one would see it, it would be just like painting the pilot inside a plastic airplane model: you'd know it was there. What would you have?

Not imaginative enough for you? Suggestions in the comments, then. [BBGadgets]

@Everyone. I live very close to Canada, and here we just consider them a neighbor or even family. We got along fine until recently, which I fear is due mostly to our current administration, and I hope that situation is remedied come November. Yes, many Americans think all Canadians live in igloos and only want us to send them money for cheap Viagra. Many Canadians think we want them to become part of US. No way do we want Quebec, though the rest of you guys would be welcomed. Till then, lets all peace out and recall how much good we do each other.
