Experimental analysis. (a) Infrared spectra of β2M peptide fibril in the amide I and II regions. Blue: non-irradiation peptide; green: peptide after irradiation at 5.0 µm; violet: peptide after irradiation at 6.5 µm; red: peptide after irradiation at 6.1 µm. (b) Deconvolution spectra before irradiation. Blue: α-helix; red: β-sheet; green: β-turn; violet: other conformation; light blue: total spectra. (c) Deconvolution spectra after irradiation at 6.1 µm. (d) Protein secondary conformation analysis before (non-irradiation) and after irradiations at 5.0, 6.5 and 6.1 µm. Blue bar: α-helix; red bar: β-sheet; green bar: β-turn; violet bar: other conformation. (e) Effect of laser energy fluence on the reduction of the β-sheet of β2M peptide. (f) Effect of laser energy fluence on the proportion of the α-helix of β2M peptide. |
