Supramolecular adaptive nanomotors with magnetotaxis behavior

Researchers demonstrated the design of magnetically actuated stomatocyte nanomotors, which could achieve guided autonomous motion. Going beyond the conventional top-down method to incorporate a magnetic component, they adopted a bottom-up approach which is familiar to natural systems and introduced magnetic metallic nickel in situ with the catalytic platinum nanoparticles (PtNP). In this way the geometric asymmetry of the system was not compromised and the co-presence of both nickel and platinum in stomatocytes was ensured.
