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.
