Nanites - The emerging technology

To understand nanites you have to know what is nanotechnology. So, Nanotechnology is a field of research and innovation concerned with buildings things - generally, materials and device in the scale of atoms and molecules. The ideas of nanoscience begins with the book "There's Plenty of Room at the Bottom" by Richard Feynman. The nanites are famous because sci-fi series like 'Revolution" NBC's series and Vin Diesel movie 'Bloodshot'. Nanotechnology are developed at that level yet. Nanites is name for Nanorobotics it also has other like nanoids. It is technology field creating machine or robots whose component are at or near nanometers ( 10^-9 meters ). Example of nanorobotics are sensor having a switch approximately of 1.5 nanometer, able to count approximately molecules in chemical sample and a amazing single molecule car, wheel made of Buckminsterfullerene also called as Nano Car. 

Potential use of nanotechnology is in nanomedicines. Nanotechnology provides a wide range of new technologies for developing customized means to optimize the delivery of pharmaceutical drugs. Today, harmful side effects of treatments such as chemotherapy are commonly a result of drug delivery methods that don't pinpoint their intended target cells accurately. Researchers at Harvard and MIT, however, have been able to attach special RNA strands, measuring nearly 10 nm in diameter, to nanoparticles, filling them with a chemotherapy drug. These RNA strands are attracted to cancer cells. When the nanoparticle encounters a cancer cell, it adheres to it, and releases the drug into the cancer cell. This directed method of drug delivery has great potential for treating cancer patients while avoiding negative effects (commonly associated with improper drug delivery). The first demonstration of nanomotors operating in living organisms was carried out in 2014 at University of California, San Diego. MRI-guided Nano capsules are one potential precursor to nanorobots.
