Nanoscience
The prefix “nano”is a Greek word for “dwarf”
One nanometer (nm) is equal to one-billionth of a meter
About a width of 6 carbon atoms or 10 water molecules
A human hair is approximately 80,000 nm wide
Red blood cells is 7000 nm wide
Atoms are smaller than 1 nanometer
Molecules and some proteins are between 1 nm and above
What is nano technology
Nanotechnology is the creation of USEFUL/FUNCTIONAL materials, devices and systems (of any useful size) through control/manipulation of matter on the nanometer length scale and exploitation of novel phenomena and properties which arise because of the nanometer length scale:
Definition Of Nano Robets
A nanobot is a nanotechnological robot nanomachine, also called a nanite, which is a mechanical or electromechanical device whose dimensions are measured in nanometres (millionths of a millimeter, or units of 10-9 meter).
Medical nanotechnology is often expected to utilize nanorobots injected into the patient to perform their treatment on a cellular level. Such nanorobots intended for use in medicine also might not replicate , as this would needlessly increase device complexity, reduce reliability, and interfere with the medical mission. Instead, medical nanorobots may be manufactured in carefully controlled nanofactories in which nanoscale machines are solidly integrated into a desktop-scale machine that builds macroscopic products.
Removal of the diseased area
Fatty material deposited on the arterial walls causing artery blockage, can be physically removed using nanoblades.
Physically shredding tumor can pose a great threat. The pieces can be carried to other locations and result in furthering of cancerous cells.
One effective approach to kill the cancerous cells would be to enclose the entire tumor in a nano box and destroying everything in the box.
