Uptake and release of Dexamethasone using pH-responsive poly (2-hydroxyethyl methacrylate-co-2-(diisopropylamino) ethyl methacrylate) hydrogels for potential use in ocular drug delivery
(Editions Sante, 2019-02)
pH-responsive hydrogels prepared by copolymerization between 2-hydroxyethyl methacrylate (HEMA) and 2-(diisopropylamino)ethyl methacrylate (DPA) appear to be a promising system for controlling Dexamethasone 21-disodium ...
Synthesis, characterization and slow drug delivery of hydrogels based in N-acryloyl-tris-(hydroxymethyl) aminomethane and N-isopropyl acrylamide
(Elsevier Science, 2011-04)
In this study, new hydrogels in rod shape were prepared from N-isopropyl acrylamide (NIPA), N-acryloyl-tris-(hydroxymethyl) aminomethane (NAT) and N,N´-methylenebisacrylamide (BIS). The effect of the incorporation of NAT ...
