THE SPINTRONIC SCANNER FOR CANCER DETECTION

THE SPINTRONIC SCANNER FOR CANCER DETECTION

ABSTRACT:

Spintronics is a branch of science that deals with the spin of an electron and not on its charge which electronics does. There are two spins (UP spin and DOWN Spin) like 0’s and 1’s to represent to states. The important property that spins could be directed in a particular direction, and the change in spin could be detected is used in our paper.

Cancer cells are easy to identify only when they are large in number. These cancer cells when matured results in the formation of tumor, which has to be removed by surgery. After surgery the presence of a single cancer cell would result in the growth of tumor in that part of the body.

This spintronic scanning technique is an efficient technique to detect cancer cells even when they are less in number.

The steps involved are,

1) The patient is exposed to a strong magnetic field so that his body cell gets magnetized.
2) A beam of electrons with polarized spin is introduced on the unaffected part of the body and the change in spin is detected by a polarimeter. Let it be X
3) A beam of electrons with polarized spin is introduced on the part which had undergone surgery. And the corresponding change in spin be Y
4)If X - Y = 0, it indicates that cancer cells have been removed from the body, if not it indicates the presence of traces of cancer cells and it has to be treated again for ensuring complete safety to the patient

Thus this technique efficiently identifies the presence of cancer cells in that part of the body that has undergone surgery to prevent any further development.
