Figure 3.
Fluorescence emission spectra of synthesized protein foldamers: (A) at an excitation wavelength of 342 nm, BP01 (red), BP02 (green), and BP03 (blue) showed emission at 363 and 382 nm; (B) at an excitation wavelength of 280 nm, NATA (cyan), Trp-cage (black), and VG01 (orange) showed emission at 356, 355, and 348 nm, respectively. (C) UV illumination of synthesized proteins. BP02 shows a more visible bright blue color compared to BP03.
