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. With their research, the scientists aim to investigate how natural cilia function, how they coordinate their movement, and what role they play in brain development, signal perception, and fluid movement, for example. Because the artificial cilia are soft and easy to control, they could one day be used in medical devices to help people whose natural cilia are damaged or not working properly. The fast, low-voltage motion demonstrated in their study could also inspire a new generation of tiny robots that were previously impossible at such small scales. This milestone work was published in Nature on January 14, 2026.
