The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s
Plenty of Room at the Bottom” by physicist Richard Feynman at CalTech on December 29, 1959.
Over a decade later, in his explorations of ultraprecision machining, Professor Norio Taniguchi coined
the term nanotechnology.
It wasn't until 1981, with the development of the scanning tunneling microscope that could "see"
individual atoms, that modern nanotechnology began.
INVENTOR OF NANOROBOT- Adriano Cavalcanti Known as nanorobot pioneer .
His structure used in environmental monitoring , brain aneurysm , diabetes , cancer and cardiology .
Nano ??? A prefix that means "one billionth" of something, or 0.000000001.
Nanorobotics - an emerging technology field of creating machines or robots whose components
are at or close to the microscopic scale of a nanometer (10^-9 meters).
It is concerned with construction and programming of robots with overall dimensions at the
The names nanobots , nanoids , nanites , nanomachines or nanomites can also be used.
