Scientists build tiny Biological robots from human cells

In an article on, researchers at Tufts University and Harvard University’s Wyss Institute have developed tiny biological robots, Anthrobots, from human tracheal cells. These Anthrobots, ranging in size from a human hair’s width to the point of a sharpened pencil, can self-assemble and have shown the ability to encourage neuron growth in damaged areas within a lab dish. Unlike previous Xenobots created from frog embryo cells, these Anthrobots were made from adult human cells without genetic modification. They present potential therapeutic applications for regeneration, healing, and disease treatment. These Anthrobots, lasting a few weeks before naturally breaking down, could be used for regenerative therapies using a patient’s own cells, with minimal immune response risk. They demonstrate movement, creating new shapes, and fostering neuron growth, raising prospects for diverse medical applications such as clearing plaque, repairing nerve damage, recognizing pathogens, delivering drugs, and aiding tissue healing. This breakthrough also sheds light on cellular assembly, offering insights into regenerative treatments and natural body plan development.
