Fluorescein, rhodamine, and aminomethylcoumarin acetate were linked to
PEG macromers via several different photodegrable ortho-nitrobenzyl
based linkers. The macromers were polymerized into gels through redox
polymerization using APS (ammonia persulfate) and TEMED
(N,N,N',N'-tetramethylenediamine). The rates of degradation and release
of the linked molecules were observed at different wavelengths and found
to differ for each molecule.
