Fig. 4: The immersion swelling test results of the hydrogel microarrays via a high-throughput manner.

a Schematic diagram showing the hydrogel coatings composed of zwitterion (SBMA, purple) and 2-Hydroxyethyl methacrylate (HEMA, green) monomers with PEGDMA crosslinker. Heat maps of the stability of hydrogel coatings synthesized by crosslinkers b PEGDMA (Mn ~200), c PEGDMA (Mn ~600) and d PEGDMA (Mn ~1000) in still PBS solution based on high-throughput screening assays. We evaluated five monomer compositions, including (i) 100% SBMA, (ii) 25% HEMA + 75% SBMA, (iii) 50% HEMA + 50% SBMA, (iv) 75% HEMA + 25% SBMA, (v) 100% HEMA. The numbers (white) inside the heat maps represent the crosslinker contents (wt.%); the numbers on the left of the heat maps represent the monomer contents (wt.%); the depth of color represents the different damage degrees of hydrogel coatings after the immersion swelling test.
