This document discusses nanobots and their potential medical applications. It begins with definitions of nanotechnology and nanorobotics. It then describes several types of proposed nanobots, including microbivores to destroy bacteria, respirocytes to carry oxygen like red blood cells, and clottocytes resembling platelets. The document outlines how nanobots could be used in chemotherapy to precisely deliver drugs to cancer cells while avoiding healthy cells. It reviews mechanisms for nanobot movement and detection of cancer. Potential advantages include rapid treatment and diagnosis, while drawbacks include risks of replication getting out of control and high costs. The conclusion is that nanobots may significantly improve treatment and diagnosis of diseases by reducing side effects.

4. DEFINITION
 Nanorobotics is an emerging technology field creating machines
or robots which components are at or near the scale of
a nanometre (10−9 meters).
 Nanotechnology is the science and
application of creating objects on a level
smaller than 100

5. INTRODUTION
According to Richard Feynman, it was
his former graduate student and
collaborator Albert Hibbs who
originally suggested to him the idea
of a medical use for Feynman's
theoretical micromachines
Hibbs suggested that certain repair
machines might one day be reduced
in size to the point that it would, in
theory, be possible to "swallow the
surgeon".

6. TYPES OF NANOBOTS
 Microbivore nanorobots
 Respirocyte nanorobots
 Clottocyte nanorobots
 Cellular repair nanorobots

7.  Microbivore nanorobots
These nanorobots would function similarly to
the white blood cells in our bodies, but they
are designed to be much faster at destroying
bacteria.
Microbivore(phagocytes) nanorobots are
designed so that antibodies attach to the
particular bacteria the robot is seeking.
 After bacteria attaches to an antibody, an arm
grabs the bacteria and moves it to the inside of
the nanorobot, where it’s destroyed.
 Bacteria is then discharged into the
bloodstream as harmless fragments.

8.  Respirocyte nanorobots
 These nanorobots would function in a similar way
to the red blood cells in our bodies; however,
they are designed to carry much more oxygen
than natural red blood cells.
 These respirocyte nanorobots would contain a
tank in which oxygen is held at a high pressure,
sensors to determine the concentration of
oxygen in the bloodstream, and a valve that
releases oxygen when sensors determine that
additional oxygen is needed.

9.  Clottocyte nanorobots
 Platelets stick together in a wound to form
a clot, stopping blood flow.
These robots function similarly to the
platelets in our blood.
A system of clottocyte nanorobots would
store fibers until they encounter a wound.
 At that point, the nanorobots would
disperse their fibers, which would then
come together to create a clot in a fraction
of the time that platelets do.

10.  Cellular repair nanorobots
 These little guys could be built to
perform surgical procedures more
precisely. By working at the
cellular level, such nanorobots
could prevent much of the
damage caused by the
comparatively clumsy scalpel.

11. OTHER TYPES

 NANOROCKETS
 MICROROCKETS

14. NANOBOTS IN CHEMOTHERAPY

15.  Chemotherapy kills cancer, but it also attacks healthy cells.
 This unfortunate phenomenon makes us sick and can cause permanent
damage to our bodies.
 Delivering medicine directly where it's needed not only minimizes side effects
but also makes the drugs more effective.
 That's why researchers are designing tiny robots to precisely carry drugs to
cancerous cells while leaving nearby healthy cells alone.

16.  Imagine armies of millions of miniature robots traveling through blood streams to
sneak up on cancerous cells.
 Despite admirable efforts by scientists, many technological challenges still need to
be overcome.
 To deliver drugs to cancerous cells, nanobots must: be small enough to penetrate a
tumor through blood vessels, be able to propel themselves and navigate while
avoiding obstacles, have a mechanism for detecting oxygen levels (which indicate
active cancer cells), be biocompatible, able to carry drugs, and have on onboard
power source.

18. MECHANISM OF NANOBOTS
 surgical nanobots could be introduced into the body through the vascular
system.
 after injection,each nanobot would travel to its target cell,enter the nucleus and
replace the chromosomes,then exit the cell and leave the body.
 inherited defective genes could be replaced with non-defectivebase pair.
 The function of the nanobots came from the the structure of e.coli bacteria
,which use flagella kind of filaments for the movement
 Flagella kind of particales are take and suspended in a magnetic field to swim
 It is manufactured in ultra clean rooms with not a single bacteria
 Can be moved to any loaction when it sits, at the asite it releases the drug in a
particular location

21. ADVANTAGES
 Can be used in the treatment of cancer.
 Rapid elimination of disease
 Cost of surgery is low
 No operation failure
 Faster and more precious diagnosis
 It might also produce copies of themselves to replace
worn out
 Speed up medical treatments

22. DRAWBACKS
 Replication may be out of control.
 Complicated maintenance.
 Very costly for installation.
 Nanobots should be programmed accurate otherwise may
result in harmful effects.

23. CONCLUSION
 The nanobots are used in medicines are predicted to provide a wealth.when the
severe side effects of the existing therapies are considered, the nanobots are
found to be more innovative,supportive to the treatment and diadnosis of vital
disease
