INTRODUCTION:
NANO TECHNOLOGY is “Research and technology development at the atomic, molecular and macromolecular levels in the length of approximately (1-100) nano meter range , to provide a fundamental understanding of phenomena and materials at nano scale and to create and use structures , devices and systems that have novel properties and functions because of their small and/or intermediate size.”
CANCER:
Cancer cells are different from healthy cells because they divide more rapidly than healthy cells. In addition, when cells divide at an accelerated rate, they form a mass of tissue called a tumors.
NANOTECHNOLOGY IMPROVED HEALTH CARE:
Nanotechnology may have its biggest impact on the medical industry.
Patients will drink fluids containing nano ‘’’’robots programmed to attack and ‘’’’reconstruct the molecular structure of //cancer cells and viruses to make them //harmless
ALGORITHM FOR NAVIGATION:
Step1: Marking the co-ordinates. Initialize the start command.
Step2: Feed the axis. Send command to emit ultrasound.
Step3: Wait for T seconds.
Step4: If there is no signal reflected back (or) if the reflected signal is ………….less than the threshold value , then activate the stepper motor to ………….rotate through a certain distance.
Step5: Subtract the axis value by one.
Step6 : Continue from step 4 to step 7 for both co-ordinates.
Step7: If the signal reflected back is greater than the threshold value then the
…………..Motor is de-activated.
Step8: The motor (perpendicular to motor 1) is activated. The motor 2 moves ……………through one step thus making the motor 1 to change the axis.
Step9: The motor1 is allowed to travel until next change is required.
Step10: Once the nanodevice reaches the required spot, the motor is deactivated ………….through external command.
Step11: Receives the RF radiation for T seconds that has been already calculated …………..depending upon the intensity of tumor.
HOW NANO DEVICE ESCAPES FROM IMMUNE SYSTEM?
i)Generally our immune system attacks all the foreign particles entering any part of our body.
CONCLUSION:
As per our aim we have proposed the usage of nanotechnology and the RF signal.
This method doesn’t affect the healthy cells such that the cancer affected persons healthy after the treatment.
