(a) UV-visible absorption spectra of riboflavin doped surfactant-free DNA thin solid films. The left and right insets are the absorption spectra in the UV and visible range for various riboflavin concentrations. (b) The refractive index of riboflavin doped surfactant-free DNA thin films for various riboflavin concentrations. (c) The refractive indices versus riboflavin concentration at λ = 632.8 and 530 nm. Error bars in (c) and (d) are the greater of standard errors in the ellipsometric fit and standard errors in the mean (SEM) of a number of measurements.
