Controlled Biomineralization Of Electrospun Poly(Ε-Caprolactone) Fibers For Enhancing Their Mechanical Properties, Jingwei Xie, Shaoping Zhong, Bing Ma, Franklin D. Shuler, Chwee Teck Lim Apr 2016

Controlled Biomineralization Of Electrospun Poly(Ε-Caprolactone) Fibers For Enhancing Their Mechanical Properties, Jingwei Xie, Shaoping Zhong, Bing Ma, Franklin D. Shuler, Chwee Teck Lim

Franklin D. Shuler

Electrospun polymeric fibers have been investigated as scaffolding materials for bone tissue engineering. However, their mechanical properties, and in particular stiffness and ultimate tensile strength, cannot match those of natural bones. The objective of the study was to develop novel composite nanofiber scaffolds by attaching minerals to polymeric fibers using an adhesive material-the mussel-inspired protein polydopamine-as a "superglue". Herein, we report for the first time the use of dopamine to regulate mineralization of electrospun poly(ε-caprolactone) (PCL) fibers to enhance their mechanical properties. We examined the mineralization of the PCL fibers by adjusting the concentration of HCO3 - and dopamine in …
