“…Moreover, the implementation of the proposed design in cancer cell detection results in a very high sensitivity of 2050 GHz/RIU with a FOM of 25.24 RIU -1 for basal type. Further, an average sensitivity of 2000 GHz/RIU has been obtained for other types of cancer which is higher than that reported in the recent literature [9], [11], [20], [22], [31], [53], [63], [64], [65], [66], [67], [68], [69], [70], [71].…”

Abstract-Highly sensitive triple-band metamaterial-based biosensor for different cancer cells detection is suggested and numerically analyzed. The reported sensor has a polyimide dielectric layer which is sandwiched between gold bottom plane and top metallic patches. The analyte sample covers the metallic patch where multiple resonances occur with high absorption. The resonance frequencies depend on the optical properties of the analyte sample. Therefore, the proposed sensor can distinguish between different cancer cell types such as skin cancer, blood cancer, and Breast cancer. Full vectorial finite element method is used to study the effects of the geometrical parameters with the aim to maximize the sensor sensitivity. The suggested sensor has high sensitivity of 2050 GHz/RIU (which is much higher than those suggested in the literature) with high quality factor of 55.34 in the frequency range from 4.25 THz to 4.75 THz. Further, the proposed biosensor is a label-free, and easy for fabrication using the state-of-the-art fabrication technologies.
