Many real examples of nanotechnology do exist, but others (such as nanobots) are imaginary.
Nano is very, very small.
Nanotechnology is real and can be found in applications such as clothing and sports equipment
Nanobots are not real and do not currently exist.
There are many challenges related to creating a nano-sized robot.
In the future, nanobots might exist and might be able to do useful things. Future examples of nanobots include applications in medicine.
There might be unintended consequences to creating nanobots.
