Nanodrugs have been around for some time. In fact, over 250 drugs using nanotechnology that  have been approved by the FDA and are in clinical use.

The name nanodrug or nanopharmaceuticals refers to the size of the particle that is created to house the medication. A nano is very tiny: nanoparticles are between 1 and 100 nanometers in at least one of its dimensions. It is about a thousand times smaller than any cell inside our body. What that means is they can only be seen with an electron microscope.

Doxil is the first cancer drug, invented in Israel, that uses nanotechnology to carry the chemotherapeutic drug doxorubicin. The nanotechnology helps to target the tumor more effectively than just doxorubicin alone and it also reduces the terrible side effects of doxorubicin.
