  • Syringe-based whispering gallery mode microresonator microfluidic biochem sensor
    Patent number: 8886270
    Abstract: A syringe-based whispering gallery mode sensor includes a syringe including an assembly provided its needle, the assembly including (1) an optical carrier having a reflective distal end, and (2) at least one resonator coupled with the optical carrier. This sensor may be provided in a system including a light source, a light detector, and a data analysis component. A method for determining the presence or concentration of a target substance in body fluid may be performed using such a system.
    Type: Grant
