Moreover , potassium persulfate (KPS) was employed to degrade the chitosan in acidified aqueous solutions and the results were also correlated with the fluorescence spectroscopy . Furthermore , the fluorescence intensity ratio (550nm/500nm) of the scaffolds prepared by chitosan/montmorillonite nanocomposites were employed to investigate their structure crosslinked by various content of glutaradehyde.
