Two Dimensional Photonic Crystal Based Bio Sensor for Cancer Cell Detection

Bio sensing techniques using photonic crystals in recent days is marked as the latest and the best method with accurate measured results. Photonic crystal-based biosensors are best responsive devices for detection and analysis of bio-substance that combines biological components with a physiochemical indicator. In this paper, cervical cancer cells are diagnosed using 2D photonic crystal-based biosensor. The sensor design consists of a `L' and an inverted `L' shaped linear waveguides with sensing holes. The photonic band gap ranges from 1225nm to 1656nm. The refractive index of the normal cell and the cervical cancer cell led to the corresponding shift in the intensity. The sensor design consists of reduced bandwidth, the results measured are accurate with good efficiency.
