It is urgently needed to develop composite bone scaffold with excellent mechanical properties and bioactivity in tissue engineering. Combining graphene oxide (GO) hydroxyapatite (HAP) for the reinforcement of biopolymer has emerged as a promising strategy. However, dispersion GO HAP remains be big challenge.In this present work, were combined respectively via situ synthesis reinforcing scaffold.GO nanosheets employed synthesize GO-HAP nanocomposite hydrothermal reaction, which their abundant...
KH550 organic modified MMT was incorporated into PCL to enhance the interfacial bonding and restricted movement of molecular chains in galleries through interlayer locking effect.
In order to improve the interfacial bonding between hydroxyapatite (HAP) and poly-l-lactic acid (PLLA), 2-Carboxyethylphosphonic (CEPA), a phosphonic coupling agent, was introduced modify HAP nanoparticles. After this. PLLA scaffold containing CEPA-modified (C-HAP) fabricated by selective laser sintering (frittage). The specific mechanism of that PO32− CEPA formed an electrovalent bond with Ca2+ on one hand, other –COOH ester –OH via esterification reaction. results showed C-HAP...
A synergistic antibacterial system for polyglycolic acid scaffolds was constructed by cation exchange of montmorillonite (MMT) with Cu 2+ and then intercalation cetyltrimethylammonium bromide (CTAB) into the interlayer MMT.
Poly-l-lactic acid (PLLA) possesses good biocompatibility and bioabsorbability as scaffold material, while slow degradation rate limits its application in bone tissue engineering. In this study, graphene oxide (GO) was introduced into the PLLA prepared by selective laser sintering to accelerate degradation. The reason that GO with a large number of oxygen-containing functional groups attracted water molecules transported them through interface microchannels formed between lamellar matrix....
The low cellular activity of poly-l-lactic acid (PLLA) limits its application in bone scaffold, although PLLA has advantages terms good biocompatibility and easy processing. In this study, superparamagnetic Fe3O4 nanoparticles were incorporated into the scaffold prepared by selective laser sintering (SLS) for continuously steadily enhancing activity. each nanoparticle was a single magnetic domain without wall, providing micro-magnetic source to generate tiny field, thereby generating...
Hydroxyapatite (HAP) grafted with poly( d -lactide) (PDLA) was incorporated into l (PLLA) to construct a stereocomplex, thus improving the interfacial bonding between PLLA and HAP like zip-lock structure in scaffold.
Indium phosphide (InP) is a representative of environmentally friendly quantum dots (QDs), and dot light-emitting diodes (QLEDs) based on InP QDs are prime candidates for next-generation display applications. However, there numerous nonradiative sites the surface QDs, which compromise operational stability QLEDs. Herein, we employed cysteamine (CTA) molecules post-treatment QD films, effectively passivating defects sites, thereby enhancing stability. This treatment enabled long T95 lifetime...
