The tiny robots are constructed from a blend of magnetic microparticles and polymers that are safe for the body.
A research team at Nanyang Technological University (NTU) in Singapore has developed miniature, grain-sized robots capable of carrying multiple drugs and delivering them directly to targeted areas within the human body, controlled entirely by magnetic fields.
These tiny, soft robots, designed by NTU’s School of Mechanical and Aerospace Engineering, are the first of their kind to be able to transport and release up to four different drugs in precise, reprogrammable sequences.
Inspired by the 1966 sci-fi movie Fantastic Voyage, lead researcher Assistant Professor Lum Guo Zhan remarked, “What was once sci-fi is now much closer to reality. Traditional drug delivery methods like pills or injections could one day seem less efficient next to a tiny robot that delivers drugs precisely where they’re needed.”
