  • OPTICAL FIBER FOR SENSING AN ANALYTE, METHODS OF FORMING AND USING THE SAME
    Publication number: 20220187532
    Abstract: Various embodiments may provide an optical fiber for sensing an analyte. The optical fiber may include a dielectric core wall defining a hollow space. The optical fiber may also include a cladding layer surrounding the dielectric core wall and spaced apart from the dielectric core wall. The optical fiber may further include a plurality of supports extending from the cladding layer to the dielectric core wall. A thickness of the dielectric core wall may be greater than a thickness of each of the plurality of supports. The dielectric core wall may be configured to carry an optical light for sensing the analyte.

  • SERS-active opto-fluidic photonic crystal fiber probe as biopsy needle and optofluidic sensor
    Patent number: 11071458
    Abstract: The present application discloses a surface-enhanced Raman scattering (SERS)-active photonic crystal fiber (PCF) probe including a biopsy needle in the PCF probe for integrated sample collection and SERS sensing of one or more analytes comprised in the sample. The PCF comprises solid core and a cladding region surrounding the solid core, wherein the cladding region comprises air holes functionalised by metallic nanoparticles. The application also provides a method for detecting one or more analytes using the PCF probe as well as the use of the PCF probe for the detection of one or more analytes.
