Nanobots are machines whose components are at the nano-scale (one-millionth of a millimeter), and can be designed in such a way that they have the ability to move autonomously in fluids. Although they are still in the research and development phase, significant advances are being made toward the use of nanorobots in biomedicine. Their applications are varied, from the identification of tumor cells to the release of drugs in specific locations of the body. Nanorobots powered by catalytic enzymes are among the most promising systems because they are fully biocompatible and can make use of “fuels” already available in the body for their propulsion. However, understanding the collective behavior of these nanorobots is essential to advance towards their use in clinical practice.
