TY - JOUR A1 - Steglich, Patrick A1 - Hülsemann, Marcel A1 - Dietzel, Birgit A1 - Mai, Andreas T1 - Optical Biosensors Based on Silicon-On-Insulator Ring Resonators: A Review TI - Molecules N2 - Recent developments in optical biosensors based on integrated photonic devices are reviewed with a special emphasis on silicon-on-insulator ring resonators. The review is mainly devoted to the following aspects: (1) Principles of sensing mechanism, (2) sensor design, (3) biofunctionalization procedures for specific molecule detection and (4) system integration and measurement set-ups. The inherent challenges of implementing photonics-based biosensors to meet specific requirements of applications in medicine, food analysis, and environmental monitoring are discussed.
