Fig. 6From: Spectroscopic analysis of mushrooms by surface-enhanced Raman scattering (SERS)PCA analysis of the Raman-SERS spectra of the six mushroom species used in this work. The PCA scores of the first two principal components PC-1 (71.40% of total variance) and PC-2 (15.20% of total variance) indicate the formation of three distinct clustersBack to article page
