Silicon photonics-based biosensor for multiplex detection

Our goal is to research, develop and commercialize an advanced biosensor that detects many different pathogen infections and immunity for diseases such as COVID-19. We are using a new sensor technology realized with semiconductor manufacturing technology (silicon photonics) and integrated optics and electronics. Our hope is that our sensors can provide answers to individuals, to industries, to governments, and to policy makers. In the long term, testing for emerging diseases will be an important global need: our multiplexed sensors will be low cost (estimated $20 in volume), disposable, usable in the field (point of care setting), and will connect via Bluetooth to a mobile device. The proposed project over the Accelerate and Elevate periods will thoroughly characterize the sensors, establish a portable, automated evaluation system for demonstrating the biosensors to potential customers, and evaluate the sensors’ suitability to meet urgent market needs in point-of-care diagnostics: essential steps for device commercialization.
