Fig. 6. DNAFL changes emission color upon formation of lipoplexes with DOTAP. (a) Normalized fluorescence spectra (λex = 365 nm) of DNAFL before (orange) and after (cyan) addition of DOTAP SUVs; (b) dependence of the DNAFL spectral center of mass (SCM) on the DOTAP/DNA charge ratio; data points show the mean value ± s.e.m. (n = 3). (c) Photography and (d) image analysis of DNAFL with and without DOTAP. From the top to the bottom row: RGB segment of the photography, hue (H), saturation (S), brightness (B) and red/green ratio (R/G).
