    Herein, a refractive index sensing based on a novel design of rectangular cavity couple with defect nanorod (RCDN), using metal-insulator-metal (MIM) waveguide is suggested for biochemical application. Herein, the optimized cavity design can provide the best sensing performance. In this work, we have numerically simulated with Finite-Difference- Time-Domain (FDTD) method, by varying small change in the geometric parameter we can bring a significant shift in the sensitivity of the device, also we can manipulate the resonance wavelength. The high sensitivity of the biosensor is 2035 nm/RIU. This device can be utilized in the on-chip detection of biochemical such glucose in water and cancer cells with high sensitivity.
