title: Differentiating intrinsic SERS spectra from a mixture by sampling induced composition gradient and independent component analysis.
abstract: By generating a composition gradient on a highly uniform SERS substrate and applying independent component analysis, we demonstrate that one can extract the intrinsic SERS spectrum of individual components from SERS spectra obtained from a two-component mixture.
