Nanotechnology involves engineering systems at the nanoscale of less than 100 nanometers. Nanorobotics creates robots between 0.1-10 micrometers by using elements like carbon, hydrogen, oxygen and silicon. Nanorobots are expected to revolutionize medicine by treating conditions at the cellular level with greater precision, speed, and fewer side effects than traditional methods. They could potentially be used to remove kidney stones, tumors, blood clots, parasites, and treat conditions like diabetes and atherosclerosis. While nanorobots offer many medical advantages, their use also presents potential disadvantages like environmental hazards and unintended human DNA alterations that require further study.

2. INTRODUCTION
NANOTECHNOLOGY
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.

3. DEFINITION
Nanorobotics 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.

4. STRUCTURE OF
NANOROBOTICS
It consists of:
Molecular sorting motor
Propellers
Fins
sensors

6. ELEMENTS
Carbon 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.

7. MECHANISM
The 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.

8. WORKING OF
NANOROBOTICS

9. ADVANTAGES
Rapid elimination of disease
Faster and more precise diagnosis
Non-degradation of treatment agents
High operational speed
Less side effects
The major advantage of nanorobots is
their durability. Theoretically they can
remain operational for years, decades
and centuries.

10. DISADVANTAGES
Possible food chain
interruption
Lack of knowledge
Nano implements could adjust
human DNA structure
Environmental hazards

11. APPLICATIONS
In medical areas:
•Kidneys
•Tumors
•Blood clots
•Diabetes
•Atherosclerosis
•Parasite removal
In spaceships
