Hydrogels are hydrophilic polymeric networks with the ability to absorb large amounts of water without losing their structure due to its chemical or physical crosslinks . Due to their high water content, similar to that of the hydrated body tissues, hydrogels show excellent biocom- patibility emerging as one of the most promising classes of biomaterials . Traditionally, methacrylate-based hydrogels obtained through photo-polymerization processes have been widely used in the biomedical field. Among them, primary amine-functionalized methacry- lates have generated considerable interest since their pri- mary amino offer the possibility of achieving a wide number of modification reactions. Particularly, 2-ami- noethyl methacrylate monomer (AEMA) has been fre- quently employed in biomedical applications. AEMA has been grafted onto poly-e-caprolactone films for tissue engi- neering applications , whereas poly (2-aminoethyl methacrylate) (pAEMA) has been studied as a potential DNA vaccine carrier or copolymerized for the design of protein resistant polymer coatings and oral drug deliv- ery applications. Some examples of the participation of AEMA in hydrogel synthesis have been reported in the literature.Hydrogels for enzyme immobilization have been obtained by radical polymerization of AEMA and N-acryloyl-tris(hydroxymethyl) aminomethane. Allen et al. made use of the antimicrobial activity provided by the ammo- nium salts of the AEMA monomer, designing bifunctional hydrogel coatings through photo-polymerization with polyethylene glycol diacrylate. Multi-responsive hydrogels were obtained from AEMA-modified polyacryl- amide or by copolymerization with propyl acrylates, in order to exploit the hydrophilic character and the pH sensitivity the monomer. Lévesque and Shoichet copolymerized AEMA with dextran for the design of mac- roporous scaffolds, using primary amine groups for cova-lent attachment of peptides.
