Advances in treatment and earlier detection have significantly improved cancer survival rates in recent decades. But some cancers remain devastatingly lethal. For patients with glioblastoma (GBM), the most common and aggressive form of brain cancer, the average life expectancy is just 12 to 18 months after diagnosis. Only a quarter will survive more than a year, and just 5% more than five years.
At the University of Toronto, Prof Yu Sun and his team at the Robotics Institute are harnessing the potential of nanorobotics – the field of technology developing microscopically small robots – to build what could be a game changing new treatment option: “nano-scalpels” that seek out cancer cells and destroy them by spinning when activated by a magnetic field.
