A photonic crystal sensor for analysis and detection of cancer cells

In this paper, a 2D photonic crystal sensor using gratings has been designed for the analysis of Basal, Breast and Cervical cancer cells. The grating design, incorporated in the photonic crystal waveguide increases the efficiency and sensitivity of the designed sensor. The fact that index of refraction of the cancer cells differs from the normal cell, it can be differentiated and detected using optical techniques. The shift in the wavelength and intensity levels in the reflection spectrum has been observed for cancer and normal cells. FDTD method has been used for analyzing cells. MEEP simulation tool has been used for modeling and designing of sensor.
