Scientists create biologically realistic artificial cilia

Scientists at the Max Planck Institute for Intelligent Systems, Hong Kong University of Science and Technology and Koç University in Istanbul have created hydrogel-based artificial cilia that move almost exactly like real biological cilia – the closest imitation achieved so far. The researchers can program each micrometer-sized cilium to move freely in space – just like cilia in the human body. This milestone work will be published in Nature on January 14, 2026.
