Hydroxyapatite (HA)/polymer composites have been widely used in the field of bone tissue engineering. However, due to the serious aggregation of HA nanoparticles and poor phase compatibility between HA and polymer matrix, the mechanical properties of HA/polymer composites are not close to their theoretical values. In order to improve the properties of HA/polymer composites, various surface modification...
A novel PGTA diblock copolymer containing electroactive TEA and mPEG is described. Biodegradable PLLA/PGTA polymer blends are shown to be electroactive. Nanopores of different sizes can be formed on the surface of the polymer blends. An MTT assay shows that the PLLA/PGTA blends exhibited reduced cytotoxicity as compared to TEA due to the introduction of the biocompatible PLLA moiety. Cell culture...
