Researchers Develop Light-Powered Nanorobots for Bacterial Capture and Removal
Researchers have introduced sub-micrometer nanorobots that utilize light for propulsion and control, presenting a novel method for cleaning and manipulation in biological environments. These nanorobots, powered by a plasmonic directional antenna, can achieve speeds of up to 50 micrometers per second and are capable of precise steering when exposed to circular polarization. The design allows these nanorobots to capture, transport, and release bacteria, functioning as light-driven robotic cleaners. This breakthrough in nanorobotics combines unidirectional scattering for thrust with passive orientation-locking from linear polarization, enabling high-speed propulsion and precise 2D steering without complex beam steering or tight focusing.
