||Brahim S, Narinesingh D, Guiseppi-Elie A. Release characteristics of novel pH-sensitive p(HEMA-DMAEMA) hydrogels containing 3-(trimethoxy-silyl) propyl methacrylate. Biomacromolecules. 2003 Sep-Oct4(5):1224-31PubMed ID12959587
||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).
||For gels loaded by physical entrapment, the quantity of each biomolecule was determined from the difference between amounts offered to the monomeric solution prior to polymerization and the amount found in the wash solution after gel formation. The results of this study are summarized in Table 1.
