Figure 6

Overlapping TG-SERS spectra at different time points. (A) HspA1 at 1 h (black), 4 h (red) and 6 h (blue), (B) hCNTF at 1 h (black), 3 h (yellow) and 4 h (red) and (C) EnBase cultivated (EN): hCNTF (magenta) compared to blank EN BL (green) after 24 h. (D–F) Shows corresponding Raman intensities (detector counts) and A-C the normalized arbitrary Raman intensities, respectively. The image was created with OriginPro (V. 2016b and 2018b; https://www.originlab.com/index.aspx?go=Products/Origin).
