2. 21st century’s problem
• Some drugs like cancer therapy have
harsh side effects. Numerous people
experience hair loss, vomiting and
dizziness as a side effect.
• The poor or the people from the third
country who have to walk too far to reach
the nearest hospital to be treated cannot
receive the privilege of modern highly
advanced medical technology.

3. Solution to the problem
• Using nanomedicine to deliver the drugs to
an appropriate cells that need to be
treated.
• Using nanorobot to check the patient’s
health condition constantly and also to
protect our body against pathogens.

5. Improvement
Existing drugs
Diffuse
component in
all body
It brings harsh
side effect
Nanomedicine
Nanomedicine
approach the
target and
work
It can much
reduce harsh
side effect

6. Drug delivery
• Drug encapsulation : encapsulate drugs to
protect them during transit in the body.
Encapsulation include liposomes and
polymer(PLA, PLGA)
• Functional drug carriers : Nanostructure can
be controlled with a drug. Attract specific cells
and release their payload when required.
(Appropriate nanostructure : Fullerenes,
Dendrimers, nanoshells)

7. Nano Drugs
It released in the
blood steam &
get information
about it
Tissue
replacement &
repair
Treatment
devices
Surgical Aids

8. Nanorobots
• Nanodevices that will be used for the purpose
of protecting our body from the pathogens.
• The main element is Carbon ; diamond /
fullerene because of the strength and
chemical inertness.
• Diamond coating is the way to avoid being
attacked by the host’s immune system.
• Carbon is indeed outstandingly biocompatible
with living cells.

9. Nano motors
• Potent Engine
– ATP ase Motor
• it is strongest motor of molecular motors
– One hundred million motors can fit on the end
of the pin

10. Fuels for nanorobots
• Catalytic reaction
• Laser light

11. When it becomes reality…
• Respirocytes : A mechanical artificial RBC
• Collottocytes : Artificial mechanical
platelets
• Microbivores : Artificial mechanical
phagocytes
• Vasculoid : A personal nanomedical
appliance to replace human blood

12. HOW does this invention impact society
• Nano robot will became smaller and smaller
• Medicine with it will cure more diseases
• We might don’t have to go to hospital any more.
• We can get all of treatment with Nano machine
