Abstract
Biodegradable elastomers have recently found widespread application in many areas of biomedical engineering such as tissue engineering, drug delivery, and bioimaging. In particular, the recent developments in research have led to the creation of citric acid based polymers with enhanced mechanical properties, novel design strategies for crosslinking, nanoporous features, and unique photoluminescent capabilities. The present review will cover the recent patents involving citric acid derived biodegradable biomaterials within the field of biomedical engineering including poly (diol citrates) and their composites, crosslinked urethane-doped polyesters (CUPEs), poly (alkylene maleate citrates) (PAMCs), poly (xylitol-co-citrates) (PXC), and aliphatic biodegradable photoluminescent polymers (BPLPs). The synthesis, development, and applications of these novel polymers will be discussed along with the current trends and future developments in the biomaterials field.
