Optical resonator based Biomolecular sensors and logic devices

Optical resonator based biosensors are emerging as one of the most sensitive microsystem biodetection technology that boasts all of the capabilities for a next-generation lab-on-chip device: label-free detection down to single molecules, operation in aqueous environment and costeffective integration on microchips together with other photonic, electronic and fluidic components. We give a scholarly introduction to the emerging field of optical resonator based biosensing, review current applications,and explain how optical resonators are coated with biomolecules to construct logic devices. © Indian Institute of Science.
