PCA analysis of FTIR and Raman spectra of: SW480 (a and c, respectively) and SW620 (b and d, respectively) cell lines. PCA was performed based on the selected spectral FTIR and Raman regions: between 800 and 1800 cm−1. The different colors of dots correspond to following samples: control (hollow squares); cells cultured with PtAu NRs (black dots); cells cultured with PtAu NRs and irradiated by the 650 nm light (orange dots); cells cultured with PtAu NRs and irradiated by the 808 nm wavelength (red dots)
