  • METHOD AND DEVICE FOR DETECTING EXTRACELLULAR VESICLES
    Publication number: 20230043792
    Abstract: Detection system for detecting at least one extracellular vesicle in a microfluid, including a broadband light source, collimating and focusing optics, a spectrophotometer, a microfluid apparatus and an active sensing element positioned inside the microfluid apparatus, the active sensing element including a substrate, a thin metal layer deposited on the substrate and a dielectric waveguide layer deposited on the metal layer, the light source generating at least one incident beam of light in the near infrared region, the metal layer and the waveguide layer each include a plurality of waveguides, the collimating optics collimates the incident beam of light on the substrate via the coupler, the focusing optics receives at least one reflection of the incident beam of light and provides the reflection to the spectrophotometer, the active sensing element causes surface plasmon waves in the microfluid when the microfluid is injected into the microfluid apparatus and the spectrophotometer detects resonance wavelength
    Type: Application
