Modeling and Simulation of an Optical Sensor for Cancer Cell Detection

In this article, modeling of ring resonator for the identification of the various cancer cells has been proposed. The model exhibits high Q factor and high selectivity for sensing various cancer cells. The parameters of the design are optimized for sensing cancer cells in the sample based on its distinct refractive index. The proposed device has been modeled by the FDTD simulation method which confirms satisfactorily distinct resonant wavelengths for various cancer cells. The device has explored the feasibility of label-free cancer cell sensing with improved characteristics.
