Abstract
Biosensor is a device used to detect the presence of biological analyte. In this work a 2D photonic biosensor is been designed to detect the cervical cancer cell in women's cervix. The proposed sensor consists of input and output waveguide with a center ring. The quality factor Q of the proposed biosensor is 248 and the sensitivity of the measurement is 143nm/RIU. The holes in the sensor is filled with cervix blood sample cells. The proposed sensor has a band gap of 1100nm to 1680nm. The biosensor is been modelled and designed using FDTD method. The dimension of the proposed sensor is 8μm X 6μm. The change in the refractive index of the cervical cells and normal cells gives corresponding wavelength shift.
