Therefore, 2 different compositions with clear degradation behavior were chosen and prepolymerization mixtures of the exact same composition were prepared. Polymer pads of 150 µL were polymerized in triplicates under the same conditions as on the slide and swollen in PBS for one week to achieve full swelling. Afterwards the pads were irradiated with UVC light to initiate degradation, the liquefied part was removed and the mass loss over time was recorded.
