CEITEC is a research center 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. They are developed mainly through a series of chemical reactions, over a number of hours. Their form depends on their intended function, but typically have 5 to 10 layers, and range in size from 20 to 50 nanometres (no bigger than a virus).
The newly developed nanorobots have a wide range of use cases - originally developed for healthcare (as mentioned) above, they could help in areas such as wastewater treatment, soil decontamination, or replace pesticides.
