Photonic Crystal Cavities based Biosensors: A Review

The review paper is providing the brief idea of photonic Crystal Cavities (PCCs) structures and their applications for biosensing devices. The paper presents the review of different PCC structures with modified properties of sensing. For several optical sensing applications, different PCC structure with properties are described in details. The conclusion of reported work and result demonstrated that miniaturization of optical biosensors is possible by the different PCC structure. This PCC structure has flexibility in structure for different sensing applications.
