Researchers at Nanyang Technological University (NTU) Singapore have developed a groundbreaking seed-sized surgical robot, measuring only 4.4 millimeters, capable of switching between five distinct functions in less than one second. This innovative device is controlled wirelessly using weak magnetic fields and can perform tasks such as cutting biological tissue, drug delivery, gripping and storing tissue samples, and generating heat. Associate Professor Lum Guo Zhan, who led the study, highlighted that unlike typical miniature magnetic robots that are limited to one or two functions, this robot can efficiently handle multiple tasks, enhancing its utility in minimally invasive surgeries. The robot's design incorporates soft silicone-based materials with embedded magnetic particles that respond to external magnetic fields, allowing for independent movement in different areas. Laboratory tests demonstrated its effectiveness on biological tissues, and safety assessments showed minimal toxicity to human skin cells. The research team is now exploring how to integrate this technology with medical imaging and artificial organ models to facilitate its practical application in clinical settings.
