  • 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.
    Type: Grant
