Nanobots are tiny machines that can operate inside the human body at the nanoscale level. They are injected into the bloodstream and can target specific cells and organs to deliver drugs or perform other tasks. Some proposed applications of nanobots include breaking up blood clots and kidney stones, curing skin diseases, assisting with heart surgery and removing tumors. While nanobots show promise for revolutionizing medicine, there are also safety and technical challenges that need to be addressed before widespread use.

2. Nanobots
Nanobots are devices made from DNA that are so small
they can be injected into the blood stream and carry a
payload of drugs to specific cells or organs.
Nanobots are tiny machines used to cure diseases in
humans or in any organism.
Performs tasks at Nano scale dimensions.
The size of nanobots are 10‾9
Also called as nanorobots,nanomach ines,nanomites and
nanoids
Nanobots can be categorized into two groups called
autonomous robots and insect robots.
Nanobots is that they require very little energy to operate

3. • 1nm = 10−9 meter
• The prefix ‘nano’ means billionth.
• We cant see with our naked eyes
Size nanorobots are same like
viruses and blood cells

4. Types of Nanobots
1. RESPIROCYTES:
• IT WORKS AS AN ARTIFICIAL ERYTHROCYTES.
• IT TRANSPORTS OXYGEN AND CARBONDI OXIDE.
2. MICROVIBORES:
• ACTS AS AN ARTIFICIAL WHITE BLOOD CELLS.
• ALSO CALLED AS NANOBOTIC phagocytes.
• IT ABSORBS AND DIGEST THE PATHOGENS IN THE BLOOD STREAM BY
PHAGOCYTOSIS.
• CONTAINS FOUR FUNDAMENTAL COMPOUNDS.THEY ARE, I. II. III. IV. AN ARRAY
OF REVERSIBLE BINDING SITE AN ARRAY OF TELESCOPPING GRAPLLES A
MORCELLATION CHAMBER DIGESTION CHAMBER
3.CLOTTOCYTES:
• IT ACT AS AN ARTIFICIAL MECHANICAL PLATELETS.
• IT REDUCES THE CLOTTING TIME REDUCES BLOOD LOSS.
• THE CLOTTOCYTE MAY ALLOW COMPLETE HEMOSTASIS IN AS LITTLE AS ~1
SECOND, EVEN IN MODERATELY LARGE WOUNDS.

5. Adriano Cavalcanti
Adriano Cavalcanti is the
medical nanobot inventor for the
practical hardware architecture
of nanobots, which was
integrated as a model based on
nano bioelectronics for
applications in environmental
monitoring, brain aneurysm,
diabetes, cancer and cardiology.

6. Design & Consruction
• Its design is derived from bacteria called
flagellum.
• Its design to float in the bloodstream
• Components include :
1. Sensors
2. Motors
3. Manipulators
4. Power suppliers
5. Molecular Component

7. • Surgical nanobots may be introduced into
body through the vascular system.
• After injection, each nanobot would travel to
its target cell,enter the nucleus and replace
the chromosomes, or perform the intended
action, then exit the cell and leave the body.
• Inherited defective genes could be replaced
with non defective base-pair.

8. Working
• Manipulator arm driven by
detailed sequence of control
signals.
• Control signals include
temperature change etc .
• Control signals received by
robotic arm via on board sensors
using broadcast architecture.
• Assemblers are molecular
machine system perform
molecular manufacturing on
atomic scale

9. • Breaking up Blood clots , Kidney Stones , Liver Stones.
• To Cure skin Diseases and as cosmetic cream.
• Heart Surgery, Tumors.
• Neuron replacement.
• It would prevent heart attack , kill cancer cells etc.
• It would augment immune system by finding and killing
bacteria and viruses.
• It can be used as mouthwash to do all brushing and
flossing.
• Smart anti-cancer Therapeutics.
• Parasite removal.
• Targeted drug delivery.
• In treatment of Arteriosclerosis.

10. NON MEDICAL APPLICATION
Nanobots can mine garbage dumps.
Next generation dress and armors with life supporting
system.
Nano robots can be used to actively repair damaged
suit materials while astronaut is in the field.
MILITARY APPLICATIONS :By using this technology, the
military would be able to create sensor systems that
could detect biological agents.
Nanoparticles can be injected into the material on
soldiers uniforms not only to make the material more
durable, but also protect soldiers from many type of
danger situations.

12. ADVANTAGES
• Small Size.
• Inexpensive(if mass produced).
• No maintenance
• Automated
• Fast process & results are accurate.
• Painless Treatment
• Easily Disposable
• Rapid elimination of disease.
• Involves less psychological strain
• Harmful ray attack is reduced
• Individual units require only a tiny
amount of energy to operate

13. DISADVANTAGES
• May affect human health by
introducing toxicity in blood.
• Replication may become out
of control.
• The nanobots should be
accurate, otherwise harmful
effects may occur.
• Very costly for installation
purpose.
• Complicated maintenance.

14. • All of the current developments in technology directs human a step closer to
nanorobots production.
• Nanorobots can theoretically destroy all common diseases of the 20th century,
thereby ending much of the pain and suffering.
• Although research into nanorobots is in its preliminary stages, the promise of
such technology is endless.
• Nanobots are going to revolutionize the medical industry in future.
• Recent advancement in the field of Nanorobotics gives the hope of the effective
use of this technology in medical field.
• The nanorobots are used in heart surgery, due to this number of risks and side
effects behind is reduced.
• The same technique is used in various treatments like cancer, breaking kidney
stones, breaking liver stones, parasite removal only with slight modification.
• Within ten year several advancement technologies should be made from this
nanorobotics.
• Nanomachines are largely in the research-and-development phase
