Detection of Melanoma Cancer Cell by Designing a SPR Based Biosensor

This paper presents the Nano cavity Implementation of the biosensors in the detection of melanoma cancer tissue. The key challenge in the work is to provide the accuracy for the biosensors and the results are obtained. The developed design shows a path advancing field of medical aspects with the development of Nano plasmon technologies. The Surface Plasmon Resonance (SPR) technology is used, the concept depends on the refractive index of the selected slab layer. The refractive index material of the normal cancer by comparing it with the refractive index of the melanoma cancer tissue in order to know the tissue is cancerous are non-cancerous. Sensitivity for different sensor design is investigated. The overall highest sensitivity obtained is 300 nm/RIU for 1550 nm of wavelength. (paper)
