Tattooing Tardigrades

So recently, I came across this article titled “Scientist have found a way to ‘tattoo‘ tardigrades.” I was immediately intrigued and started reading.

Scientists used ice lithography, a micro fabrication technique, to tattoo tardigrades. Since tardigrades are basically indestructible, they were a good test subject. While tattooing these tardigrades, researchers applied a protective anisole layer and exposed them to an electron beam, which left behind a microscopic pattern like a tattoo. This reveals that we now have developed techniques that “could be suitable for printing micro-electronics or sensors onto living tissue.”

This technology has the potential to revolutionize microprocessors, solar cells, and even medicine. Being able to work at such a small scale level shows how far our technology has advanced. We can apply these tattooing techniques to CPU cores and capacitors, potentially increasing processing speed and power while reducing the space needed. This would drastically improve calculation speeds in computers and could revolutionize the way we manufacture electronic devices. This discovery has so many possible use cases, which makes it all the more exciting.
