The document discusses using nanorobots to fight cancer. Nanorobots are tiny machines that could be injected into patients to detect and destroy cancer cells without harming healthy cells. They would use biological sensors to locate tumors and contain enzymes to kill the cancer cells. While promising for inexpensive and painless treatment, nanorobots remain in early development stages and designing effective machines at the nanoscale is technically challenging.

1. Fight With Cancer Using Nanorobots
MITCOE E&TC DEPARTMENT

2.  Introduction
 Nanorobots
 Design of Nanorobot
 Status Of development
 Advantages
 Disadvantages
 Conclusion

3.  Uncontrolled Growth Of Cells
 Spread all over the body
 Leading Cause of Death 7.6 million
 Lung Cancer
 Stomach Cancer
 Liver Cancer

4.  Radiation Therapy
 Chemotherapy
 Kills Healthy Cells
 Fatigue
 Hair Loss

5.  Inject nanorobots
into patient
 Detect cancer Cells
 Destroy Cells
 Do not affect on
Healthy Cells

6.  Nano
Infinitesimally Small
Scale of Manufacturing
And Fabricating Materials
 NanoRobot
Tiny machine
Perform specific task

7.  Sensitive to Biological Element
 Detect body temperature ,fluids or enzymes
 Phosphatidic acid Chemotactic sensor can use
 PH responsive
 Tumor have low PH
 Transducer

8.  Receive Signal from Nanobiosensor and
Perform its job
 Contain Highly Concentrated enzymes which
will be delivered into infected cell

9.  Cant use conventional sources
 Chemical Energy
Nanorobots would hold small chemical
Supply
Become fuel source when combined
with blood

10.  Float freely inside the body
 Detect the tumor effectively
 Bottom-up approach
 Assembling structures atom by atom or
molecule by molecule

11.  Typically 0.5 to 3 micron
 1-100 nm parts
 Interior : Vacuum environment
 Exterior : Not affected by chemical liquids of
our body

12. ▶ 70-nm attack robots
▶ Attaches to the cancerous
cell's surface
▶ Carry siRNA deactivates
protein production
▶ Starving malign cell to
death. Tumor 500 nm

13.  Small Size
 Inexpensive(if mass produced)
 No maintenance
 Automated
 Painless Treatment
 Easily Disposable

14.  Should be Accurate if not harmful effect
occurs
 Initial Design Cost high
 Very complicate design

15.  Recent advancement in the field of
Nanorobotics gives the hope of the effective
use of this technology in medical field.
 Thus in future nanoterobots will play an
important role
