flag Researchers in China create "ice tattoo" tech for precise nanoscale patterns on living organisms.

flag Researchers at Westlake University in China have developed an "ice tattoo" technology that creates precise nanoscale patterns on living organisms with high precision and biocompatibility. flag This new method uses ice instead of traditional photoresist materials, reducing contamination risks and enabling biological applications. flag The technology was tested on tardigrades and could advance the development of medical nanodevices and microrobots.
