In vivo degradation behavior of porous composite scaffolds of poly(lactide-co-glycolide) and nano-hydroxyapatite surface grafted with poly(L-lactide)
Intramuscular implantation test of 20w showed that porous composite scaffolds of surface grafted g-HAP/PLGA and ungrafted n-HAP/PLGA presented slower degradation and higher mineralization compared to that of pure PLGA. Compared with n-HAP/PLGA, g-HAP/PLGA showed an improved absorption and biomineralization because of its improved distribution of g-HAP nanoparticles in PLGA matrix. &nb...

In vivo mineralization and osteogenesis of nanocomposite scaffold of poly(lactide-co-glycolide) and hydroxyapatite surface-grafted with poly(l-lactide). Biomaterials, 2009,30: 58–70
[Abstract]: Nanocomposite of hydroxyapatite (HAP) surface-grafted with poly(l-lactide) (PLLA) (g-HAP) shows a wide application for bone fixation materials due to its improved interface compatibility, mechanical property and biocompatibility in our previous study. In this paper, a 3-D porous scaffold of g-HAP/poly(lactide-co-glycolide) (PLGA) was fabricated using the solvent casting/particu...

A branching point thermo and pH dual-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N-diethyl aminoethyl methacrylate)
We report the design and synthesis of a branching point stimuli-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N-diethylaminoethyl methacrylate) through combined“A2+BxC” (x > 2) double monomer polymerization and parallel click reaction. The results of ultraviolet-visible
spectrophotometry and dynamic light scattering (DLS) indicated that the resultant ...

Interchain Hydrogen-Bonding-Induced Association of Poly(acrylic acid)- graft-poly(ethylene oxide) in Water
Poly(acrylic acid)-graft-poly(ethylene oxide) (PAA-g-PEO) in aqueous solutions shows one fast and one slow relaxation mode in dynamic light scattering (DLS), but the mixture ofPAAandPEO(PAA/PEO) in aqueous solution only has a single fast mode. The effects of pH, polymer concentration, and salt concentration on these two modes have been investigated using laser light scattering (LLS), v...

Biodegradable Poly(ε-caprolactone)-g-Poly(2-hydroxyethyl methacrylate) Graft Copolymer Micelles as Superior Nano-Carriers for “Smart” Doxorubicin Release
Biodegradable micelles were prepared from poly(ε-caprolactone)-g-poly(2-hydroxyethyl methacrylate) (PCL-g-PHEMA) graft copolymers and investigated for controlled release of doxorubicin (DOX). PCL-g-PHEMA copolymers were readily obtained by controlled ring-opening copolymerization of acryloyl cyclic carbonate and ε-caprolactone, Michael-type conjugate addition reaction with cysteami...
