Method An amphiphilic hydrogel of poly(2-hydroxyethyl methacrylate) cross-linked with tetraethyleneglycol diacrylate (TEGDA) was synthesized to contain the hydrophobic monomer 3-(trimethoxy-silyl) propyl methacrylate (PMA) and the pH-responsive, hydrophilic monomer N',N'-dimethylaminoethyl methacrylate (DMAEMA).
Comments For gels loaded by imbibition, the quantity of each biomolecule in the loading solution was determined before and after immersion of the gel slab. The difference between these two amounts represented the quantity of biomolecule loaded into the gel.
