3. What is Nanotechnology ?
Nanotechnology is the engineering of functional systems at the
molecular scale. In its original sense, 'nanotechnology' refers to
the projected ability to construct items from the bottom up, using
techniques and tools being developed today to make complete,
high performance products

5. Definition Of Nanomedicine
• Nanomedicine is defined as the monitoring, repair,
construction and control of human biological systems at
the molecular level, using engineered nanodevices and
nanostructures.
• The detection and controlled manipulation of human
biological system at the molecular level via engineered
nanodevices and/or nanostructures.

Nanodevice”

7. Why Nanomedicine ?
•Diseases are mainly caused by damage at the molecular
and cellular level
•Today’s surgical tools are huge and imprecise in comparison

surgical tools”

9. Goals of Nanomedicine
End goal of nanomedicine is improved diagnostics,
treatment and prevention

10. Goals of Nanomedicine
Ultimate goal is to integrate detection, diagnostics,
treatment and prevention of disease into a
personalized single platform

11. Recent and future breakthroughs in
medicine
Nanotechnology holds key to a number of recent and future
breakthroughs in medicine

12. Cancer Treatments
• Because of their small size, nanoparticles
can pass through interstitial spaces
between necrotic and quiescent cells.
• Tumor cells typically have larger
interstitial spaces than healthy cells
• Particles collect in center bringing
therapeutics to kill the tumor from inside

13. Detection of Cancer

• On the left, cancer cells fluorescence.
• On the right, healthy cells show minimal
fluorescence.

17. Advantages of Nanomedicine
•Drug delivery to the exact location.
•lower side effects.
•Molecular targeting by nanoengineered devices
•Detection is relatively easy.
•No surgery required.
•Diseases can be easily cured.

18. Disadvantages
•Not fully practical yet.
•High cost.

19. Major Areas of Development of
Nanomedicine
• Prevention and control
• Early detection
• Imaging
• Multifunctional Therapeutics

20. Conclusion
•Although realization of the full potential of
nanomedicine may be years or decades away,
recent advances in nanotechnology-related drug
delivery, diagnosis, and drug development are
going to change the medicine landscape.
•Nanotherapies could be, in the long term, much
more economical, effective and safe and could
greatly reduce the cost of current medical
procedures.
•So, Nanomedicine is the future of medicine.
