(A) Schematic mapping of the various irradiation spots on the different phalanxes. (B) Picture of a finger after irradiation. The white dehydrated spot marks the irradiation zone. (C) Averaged MS spectrum recorded from the same phalanx of a man versus a woman. (D) Principal component analysis (PCA) performed from the MS spectra of all the volunteers and showing the discrimination according to gender. (E) Hierarchical Clustering (HC) performed from the significant masses (p < 0.05) according the gender.
