摘要

•SERS is employed to evaluate antifungal activity of Zinc and selenium organometallic compounds.•Silver nanoparticles are used as SERS substrates.•SERS spectral features are associated in comparison with different ligands and their respective ligands.•Principal components analysis (PCA) is found helpful for the differentiation between SERS spectral data of silver and zinc NHC complex exposed A. niger and unexposed control fungus.•PLSDA model is validated and can be used for the classification of Se-NHC and Zn-NHC complexes.
