Nano is a prefix that means one billionth. At this size, we’re talking about the atomic level. Bot, short for robot, is a programmed machine that executes tasks without human involvement. Now imagine the power if we combined these two ideas. That is what makes nanobots, a subset of nanotechnology, so powerful, particularly in the field of medicine where atomic level substances create a system.

One of the most basic applications for nanobots is a biological research tool. Given their size, nanobots can navigate cells giving researchers a more detailed understanding of a cell’s properties and functions. This would ultimately give us a deeper understanding of our body’s systems and help uncover some of its secrets.

Another possible application within the medical field for nanobots is precision medicine. Nanobots have been tested for their capability to migrate within a biological system. Given their movability, nanobots could enhance drug delivery by targeting specific areas of the body. Hypothetically, nanobots could speed up treatments which could be key to lowering costs for those affected with illnesses as common as the flu as well with chronic diseases like diabetes.

Water purification is another nanotech initiative that has already started but still has room to grow. Nanobots have the ability to manipulate atoms which allows them to soften water and remove contaminants, both chemical and biological. Similarly, testing has begun for the cleaning of contaminated soil by nanobots. These robots would be able to purify soil and water at an atomic level in a way that could be sustainable and effective. Such an initiative could raise the standard of living for so many people who are affected by contaminated elements.

Nanotechnology has proved itself to be promising with its applicability in a vast number of fields. As research continues and nanobots become a more mainstream technology, I don’t doubt that they could change lives and societies.
