font size="1"> In this study, new hydrogels in rod shape were prepared from N-acryloyl-tris-(hydroxymethyl) aminomethane (NAT) using three different crosslinking agents: poly(2-methyl-2-oxazoline) bismacromonomer (BM), ethylene glycol dimethacrylate (EGDMA) and N,N´-methylenebisacrylamide (BIS). Dimethylformamide (DMF) was used as solvent and 2,2´-azobisisobutyronitrile (AIBN) as initiator. Polymeric matrices with different properties were obtained by free radical polymerization by changing the crosslinker (BM, EGDMA or BIS) or the concentration of BM. The hydrogel structures were characterized by high resolution magic
