Organized structures based glucose monomers studied using Delayed Luminescence

Many studies have shown that the Delayed Luminescence (DL) is a sensitive indicator of the functional state of a biological sample. Moreover, it has been shown that the DL intensities and kinetics depend on impinging light intensity, structure size and temperature. To gain new insights into the mechanisms responsible for DL, we studied DL emission from alpha-D-glucose, starch and cellulose. Starch and cellulose are polymers having the same glucose-based repeat units differently orientated. Experimental results showed significant difference in DL kinetics, intensities, spectral emission for the different samples and nonlinear dependence of DL emission on light source intensity.
