Biomedical engineering has taken a massive leap forward as researchers from the University of Canterbury successfully demonstrated the use of highly focused laser beams to control swarms of micro-robots. These tiny machines, measuring just one-hundredth the width of a human hair, can be trapped, moved, and orchestrated with pinpoint precision. The primary objective of this micro-robotics technology is to manipulate individual living cells to study their micro-level interactions. This breakthrough is set to revolutionize tissue engineering, offering the foundational control needed to successfully 3D-print fully functional human muscles and complex biological organs, while paving the way for targeted drug delivery systems in advanced cancer therapies.
