Scientists in Brno are developing miniature robots – no bigger than a virus and so invisible to the naked eye – capable of performing surgery. Due to their size, the so-called nanorobots can reach all but inaccessible places in the human body. “Nano” is a Greek prefix meaning “one-billionth”, and nanotechnology refers to devices that are a few billionths of a metre in size. The Central European Institute of Technology, or CEITEC, is where life sciences and nanotechnologies meet. CEITIC was founded by a group of Brno-based universities and national research institutes specializing in everything from physics to veterinary medicine. Among the ongoing projects there is one developing nanorobots capable of facilitating eye surgery and other delicate operations, attacking cancer cells or for deep-cleaning of dental canals.
