Amination of Polymeric Braid Structures to Improve Tendon Healing: An Experimental Comparison
Macromolecular Materials and Engineering, Volume 308, Issue 1, January 2023., 2023 Poly(ethylene terephthalate) (PET) and poly(lactic acid) (PLA) are polymers useful in tendon repair, though with minimal success. There is a need to improve such scaffolds' design and physical–chemical nature. The work concerns functionalization of PET/PLA braids to incorporate amine groups in the braids' surface, improve cell adhesion, and ...
