Thin films containing metal (gold, silver, etc.) nanoparticles are important platforms for molecular sensing based on the localized surface plasmon resonance (LSPR) phenomenon. To support their use in high-resolution LSPR spectroscopy systems, a software package, called NANOPTICS, was developed. It performs a statistical analysis of the LSPR band of the films, employing central moments of the normalized spectral distribution of optical transmittance. LSPR band parameters, signal-to-noise ratio and refractive index sensitivity are the outputs. It is shown that NANOPTICS can be a powerful tool to perform fast diagnostics of LSPR-based sensors' sensitivity and to analyse their response to target analytes. (C) 2020 The Authors.
