INTRODUCTIONNANOTECHNOLOGY

Nanotechnology is the engineering of functional systems that deals with the dimensions of less than 100 nanometers, especially the manipulation of individual atoms and molecules.

A nanometer is one billionth of a meter.

DEFINITIONNanorobotics is the technology of creating machines or robots at or close to the scale of a nanometer (10-9 meters).

Nanorobots would typically be devices ranging in size from 0.1-10 micrometers.

The nanorobots are expected to revolutionize the medical industry, with the ability to treat at a cellular level and make medical applications easy and effective.

STRUCTURE OF NANOROBOTICS

It consists of:Molecular sorting motorPropellersFins sensors

ELEMENTSCarbon is the principle element comprising the bulk of a medical nanorobot, probably in the form of diamond or diamondiod nanocomposites.

Many other light elements such as hydrogen, sulphur, oxygen, nitrogen, fluorine, silicon etc., will be used for special purposes in nanoscale gears and other components.

MECHANISMThe attached bacteria by rotating their flagella push the microscope to forward by using different chemicals the on/off motions of micro robots are controlled.

These chemicals bind to the flagella motor and restrict their movement.

Mainly used chemicals are EDTA(Ethylene diamine tetra acetic acid) used to restart their motion and copper ions used to stop their motion.

WORKING OF NANOROBOTICS

ADVANTAGESRapid elimination of diseaseFaster and more precise diagnosisNon-degradation of treatment agentsHigh operational speedLess side effectsThe major advantage of nanorobots is their durability. Theoretically they can remain operational for years, decades and centuries.

DISADVANTAGESPossible food chain interruptionLack of knowledgeNano implements could adjust human DNA structureEnvironmental hazards

APPLICATIONSIn medical areas:

•Kidneys•Tumors•Blood clots•Diabetes•Atherosclerosis•Parasite removal

In spaceships
