Split ring resonator biosensor-an innovative design and analysis

In this study, a split ring resonator (SRR) design is simulated for the detection of different cancer cells in biosensing application using COMSOL Multiphysics software. Finite element method (FEM) is used to evaluate electric field distribution in SRR. The analysis of biosensor is done in microwave region. Small change in dielectric constant produces shift in resonant peak of SRR so this biosensor can be used for the detection of different types of cancer cells like Hela, PC12, MDA-MB-231, MCF-7, Jurkat. The advantages of this biosensor are low cost manufacturing and level free sensing with appropriate sensitivity.
