  • Detailed angular mapping to identify regions of maximum sensitivity.

    • Main Results:

    • Demonstrated the sensing potential of the imprint-fabricated plasmonic crystal.
    • Identified maximum sensitivity to surface chemical binding events near specific regions of the plasmonic Brillouin zone.
    • Observed that sensitivity maxima correlate with the convergence of multiple surface plasmon polariton (SPP) modes.

    Conclusions:

    • The developed plasmonic sensor exhibits high sensitivity due to the convergence of SPP modes.
    • Simple and low-cost fabrication methods make this device suitable for widespread use.
    • This technology holds significant promise for high-performance chemical and biological sensing applications.
