crosslinked by poly(ethylene glycol)dimethacrylate (Mw = 750 Da) (PEGDMA 750) together with an oxygen scavenger system based on glucose oxidase (2.3 µM) and glucose (5.8 mM), which has been investigated on the DMA (Fig. ). First step to investigate was the polymerization time. For this, hydrogels with different PEGMA:SAMA molar ratio (6:1 to 3:4) crosslinked with 10 mol% PEGDMA were polymerized on a scale of 130 nL per gel pad.
