Plots (A,D) show the time evolution of the peak position v(t) of the emitting fluorophores for collagen and collagen–glucose, respectively, excited at 280 nm. The time evolution of fluorescence intensity C(t) is shown for collagen and collagen–glucose in plots (B,E), with each spectra normalized. The inset shows the same data over a longer time range. The six lines show day 0, day 7, day 14, day 21, day 28, and day 56. Plots (C,F) show the changes in σ parameters (see eq 5). Part (G) shows (t) for collagen and collagen-glucose on day 0 for comparison, with the error bars showing the 90% confidence intervals for the fitted values.
