(a)
PCA score of isolation of the 24 and 48 h post‐irradiated samples from each other,
(b)
Loading profile for the 24 and 48 h post‐irradiated samples in the presence of the drug,
(c)
Frequency repetition profile of the best wavelength for the separation of the 24 and 48 h post‐irradiated samples,
(d)
