## Description

- description: 'Surface-enhanced Raman Scattering spectroscopy has transformed trace
    analyte detection by harnessing localized surface plasmon resonance. Hybrid plasmonic–photonic
    modes have been shown to further improve enhancement factors by tailoring the
    resonant wavelength. Here, we use a surface lattice resonance-based platform tuned
    to amplify the Stokes-shifted Raman emission band produced by using capillarity-assisted
    Ag nanoparticle assembly. Additionally, we transferred graphene onto these substrates
    to evaluate its effect on the long-term retention of the analyte signal. We monitored
    the Raman signature of 2-naphthalenethiol on substrates with and without transferred
    graphene sheets over 1 year since initial exposure. Signal intensities from both
    the unprotected (U) and graphene-protected (G) samples were projected onto the
    principal components to evaluate the spectral traits and monitor how the spectra
    change over time. The results showed that both U and G samples initially exhibited
    a detection score of approximately 80%. While the U sample completely lost its
    Raman signal after 300 days, the G sample retained a detection score of about
    30%, which remained stable even after 344 days. We attribute the retained signal
    on the G substrate to two phenomena: (i) graphene prevents the degradation of
    plasmonic particles and (ii) helps retain the analyte on the substrate. Moreover,
    the ratio of Raman peaks coinciding with the lattice resonance vs off-resonance
    peaks was higher compared to a reference measurement. This underscores the potential
    of graphene–silver hybrid platforms for applications requiring sustained analyte
    signature, where a long shelf life and prolonged detection over time could facilitate
    repeated measurements or continuous monitoring without the need for frequent sample
    replacement on site.'
