  • 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

  • Plasmonic enhancement of whispering gallery mode biosensors
    Patent number: 8493560
    Abstract: A sensor for determining the presence or concentration of a target entity in a medium is described, and includes (a) an optical waveguide; (b) a microresonator optically coupled with the optical waveguide such that light within the optical waveguide induces a resonant mode within the microresonator at an equator region (or a mode volume); and (c) at least one plasmonic nanoparticle adsorbed onto a surface area of the microresonator within the equator region (or the mode volume) such that light inducing a resonant mode within the microresonator also causes a plasmonic resonance in the at least one plasmonic nanoparticle. Detection methods for using such sensors are also described. Finally, methods, involving the use of carousel forces, for fabricating such sensors are also described.
