Optical Resonator Based Biomolecular Sensors and Logic Devices

Abstract

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 cost-effective 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.
