Synthesis and Characterizations of Biodegradable Polyurethane Microspheres with Dexamethasone for Drug Delivery
E-mail:
This manuscript reports on the synthesis of biodegradable polyurethanes (PU) using poly(ε-caprolactone) diol and fabrication of microspheres containing dexamethasone (DEX). Biodegradable PUs with different isocyanate ratios were successfully synthesized using PCL diol as a polyol. The PU with a high isocyanate ratio exhibited a low average molecular weight, high melting point, high Young’s modulus, low tensile strength, low elongation to break, low hydrolytic degradation rate, and fast release profile of DEX. These results can be used to optimize properties so as to be suitable for specific applications. Our next goal is to evaluate the performance of PU microspheres as an injectable cartilage filler through in vitro and in vivo studies. In addition, the biodegradable PUs can be used for tissue-engineered scaffolds using three-dimensional printing.
