Spermidine-Cross-linked Hydrogels as Novel Potential Platforms for Pharmaceutical Applications

“…Since time immemorial, the manipulation of biomaterials played an important role in the biomedical field, although it was not until the 1960s that their evaluation and development was undertaken in a rigorous manner. From then on, the interest arisen by this type of materials has highly increased [1][2][3][4][5][6][7][8] and nowadays new biomaterials continue being discovered, designed, and created. [9][10][11] An important position among biomaterials is occupied by hydrogels, which are three-dimensional networks formed by highly hydrophilic polymers able to imbibe great amounts of aqueous fluids.…”
