Abstract
This paper presents a light-propelled nanomotor built by introducing gold nanoparticles (Au NPs) onto biodegradable bowl-shaped polymersomes (stomatocytes). These nanomotors exhibit controllable motion and velocities up to 125 µm s⁻¹, exceeding previously reported speeds. Cryogenic transmission electron microscopy (cryo-TEM) and cryo-electron tomography (cryo-ET) reveal that the non-uniform Au NP distribution on the stomatocyte surface causes this directional movement. The nanomotors' motility is successfully used for active cargo delivery into living cells, showcasing potential biomedical applications.
