PAs are a hydrolytically unstable class of biodegradable polymers that are usually aliphatic, aromatic, or a mixture/blend of two components. PAs have demonstrated biocompatibility and excellent properties such as CR characteristics. PAs are synthesized by dehydration of the diacid or mixture of diacids by melt polycondensation photo cross-linking (Figure 2.51) [374]. 

Hydrogels are one of the most common tissue engineering scaffolds. In its most basic form, a hydrogel consists of a solution of hydrophilic polymer, suspended in water, that forms a gel on cross-linking. Cross-linking may be induced by a radical initiator, usually photo- or heat activated, which cross-links linear or branched polymers. As with electrospinning, there are many polymers and polymer blends that have been made into hydrogels (Li et al., 2015 Lin and Li, 2014 Sun et al., 2014).
