Light Could Propel Nanorobots on a “Fantastic Voyage” Through the Human Body

Facebook Twitter LinkedIn Email Comments
Light-driven synthetic nanorobots, comparable in size to a blood cell, could someday travel through the human body to aid surgeons in the removal of tumors and deliver targeted medications. A nanorobot that uses light as its propelling force has been demonstrated by a research team at Hong Kong University (HKU). The nanorobots, which were developed over a three-year period, have a novel nanotree structure, composed of two common, low-cost semiconductor materials: silicon and titanium oxide. To build the structure, the silicon and titanium oxide materials were shaped into nanowire and...Read full article
