Design and modelling of photonic sensor for cancer cell detection

This paper tells about the early detection of cancer cell by using photonic band gap method. System level cancer cell detection has been done with the dielectric constant(at optical frequency) as the input. Comparison of normal cell and cancerous cell has been done and a precise frequency shift has been observed. The input dielectric constant values of normal cell varies from 1.8225 to 1.8769 and for cancer cell it varies from 1.9376 to 1.9628. Even though the change in the input is very small, a micron change in the frequency has been observed. Thus, photonic crystal based sensor will differentiate the normal cells from cancerous cell.
