These Tiny Robots 50x Smaller Than a Hair Can Hunt and Move Bacteria

Researchers at Julius-Maximilians-Universität Würzburg built submicrometer nanorobots that move using photon recoil and can be steered with polarized light.

The devices can hunt, capture, transport, and release bacteria with high precision in microscopic environments.

The study, published in Nature Communications, shows a practical method for manipulating bacteria at very small scales.

Potential uses include microbiology research, biomedical applications, and future microscopic cleaning tools.
