Area of Science:

  • Nanotechnology
  • Plasmonics
  • Materials Science

Background:

  • Plasmonic sensors are crucial for biosensing but often require complex setups.
  • Detecting ultra-low refractive index changes is essential for early disease diagnosis.
  • Vanadium dioxide (VO2) is an innovative phase-change material with unique optical properties.

Purpose of the Study:

  • To demonstrate a highly sensitive plasmonic metasensor for detecting minute refractive index variations.
  • To utilize the Goos-Hänchen (GH) lateral shift for phase signal detection in plasmonic sensing.
  • To explore the potential of VO2 as a sensing layer for biosensing applications, including cancer biomarker detection.

Main Methods:

  • Fabrication and characterization of a plasmonic metasensor with a VO2 sensing layer.
  • Measurement of the Goos-Hänchen lateral shift at the sensing interface for phase detection.
  • Utilizing surface plasmon resonance (SPR) excitation at resonance for enhanced sensitivity.
  • Electromagnetic simulations using Comsol (finite element analysis) and MATLAB (transfer matrix method).

Main Results:

  • Achieved ultra-low refractive index change detection (Δn = 10⁻¹⁰ RIU).
  • Demonstrated high sensitivity of 1.393 × 10⁸ μm/RIU based on GH lateral shift.
  • Obtained significant GH shifts (2.997 × 10³ μm) at the resonance condition.
  • Validated sensor performance through SPR curve analysis and electromagnetic simulations.

Conclusions:

  • The developed plasmonic metasensor with VO2 offers a sensitive and feasible platform for detecting ultra-low refractive index changes.
  • The direct measurement of GH shift provides a simpler alternative to complex phase-singularity detection methods.
  • This technology holds promise for the development of advanced biosensors for early cancer biomarker detection.
