Optical properties of DNA and DNA-riboflavin in aqueous solutions. (a) Refractive index dispersion in the visible to near IR spectral range. (b) Refractive index increments of DNA and DNA-riboflavin solutions relative to that of de-ionized water. The concentrations of DNA and riboflavin were 0.25 wt. % and 10–130 μM, respectively. (c) Fluorescence excitation spectra and (d) emission spectra of riboflavin aqueous solutions are compared with and without DNA. Error bars in (a) and (b) are standard errors in the mean (SEM) in the measured angle.
