Tardigrades take extreme living to another level, thriving in the toughest conditions. These animals (nicknamed “water bears” for their rotund figure) live practically everywhere and can endure any ordeal thrown their way, from subzero temperatures to cosmic radiation. This unparalleled durability is what makes them the perfect candidate for microscopic tattoos, as shown in a new study published in the American Chemical Society’s Nano Letters.
In this study, researchers have revealed a way for tardigrades to be tattooed, but not just for style points. The tiny tattoos given to the creatures were meant to test a procedure that could create micro- and nanoscale devices for living matter, a crucial advancement for biomedical fields.
