  • Publication number: 20140315760
    Abstract: Photonic devices, systems, and methods for detecting an analyte in a biological solution (e.g., whole blood) are provided. Representative photonic devices are optical ring resonators having nanoscale features and micron-sized diameters. Due to the compact size of these devices, many resonators can be disposed on a single substrate and tested simultaneously as a sample is passed over the devices. Typical analytes include blood cells, antibodies, and pathogens, as well as compounds indicative of the presence of blood cells or pathogens (e.g., serology). In certain embodiments, blood type can be determined through photonic sensing using a combination of direct detection of blood cells and serology. By combining the detection signals of multiple devices, the type of blood can be determined.
