This review summarizes the current research status on biodegradable metals as bone implants, including their biodegradability, mechanical properties, and biocompatibility.
It is critical to develop a fabrication technology for precisely controlling an interconnected porous structure of scaffolds mimic the native bone microenvironment. In this work, novel combined process additive manufacturing (AM) and chemical etching was developed fabricate graphene oxide/poly(L-lactic acid) (GO/PLLA) with multiscale structure. Specially, AM used network pore sizes hundreds microns. And in sodium hydroxide solution constructed pores several microns or even smaller on...
A tetragonal polyvinyl alcohol (PVA) scaffold with 3D orthogonal periodic porous architecture was fabricated via selective laser sintering (SLS) technology. The under the power of 8 W, scan speed 600 mm min(-1), spot diameter 0.8 and layer thickness 0.15 mm. microstructure analysis showed that degree crystallization decreased while PVA powder melts gradually fuses together completely increasing. Thermal decomposition would occur if further higher (16 W or in case). controllable totally...
Blending Polyetheretherketone (PEEK) with Polyvinyl alcohol (PVA) is promising to obtain a composite scaffold combining the excellent biomechanical properties of PEEK and remarkable degradability PVA. However, weak interfacial bonding between nonpolar polar PVA would result in poor mechanical properties. In this study, owing its unique amphiphilic properties, graphene oxide (GO) was employed enhance PEEK/PVA scaffolds that were fabricated by laser 3D printing. On one hand, large π-conjugated...
The insufficient mechanical strength and slow degradation rate of poly-<sc>l</sc>-lactic acid (PLLA) limit its applications in bone repair.
Poly-L-lactic acid (PLLA) lacks osteogenic activity, which limits its application in bone repair. Zinc (Zn) is widely applied to strengthen the biological properties of polymers due excellent activity. In present study, Zndoped mesoporous silica (Zn-MS) particles were synthesized by one-pot hydrothermal method. Then, induced into PLLA scaffolds prepared selective laser sintering technique, aiming improve their Our results showed that possessed rosette-like morphology and uniform structure,...
The water-responsive shape memory mechanism model of a TPU specimen was proposed, in which the reversible hydrogen bonding between water molecules and hard segments formed after wetting disappeared drying.
Although barium titanate (BaTiO
A NH 2 -MXene/PLLA nerve conduit with a conductive network structure is constructed by laser additive manufacturing, which can generate electrical signals driven electromagnetic induction, and the generated promote differentiation of cells.
Poly(<sc>l</sc>-lactide) (PLLA) is a promising bone repair material owing to its good biocompatibility and natural degradability, but lack of bioactivity insufficient mechanical property restrict further application.
The incorporation of carbon nanotubes (CNT) and hydroxyapatite (HA) into biopolymer as bone scaffold is expected to combine the excellent mechanical properties CNT bioactivity HA. However, dispersion HA in a challenge. In this paper, under condition hydrothermal reaction, nanoparticles were situ synthesized on surface carboxyl multi-walled prevent their aggregation poly (ε-caprolactone) (PCL) prepared by selective laser sintering (SLS). mechanism synthesis was that functional groups cCNT...
Scaffolds loaded with antibacterial agents and osteogenic drugs are considered essential tools for repairing bone defects caused by osteomyelitis. However, the simultaneous release of two leads to premature osteogenesis subsequent sequestrum formation in pathological situation unthorough antibiosis.In this study, a spatiotemporal drug-release polydopamine-functionalized mesoporous silicon nanoparticle (MSN) core/shell drug delivery system silver (Ag) nanoparticles dexamethasone (Dex) was...
Combining poly (L-lactic acid) (PLLA) with thermoplastic polyurethane elastomer (TPU) can integrate the advantages of excellent biocompatibility and intrinsic shape memory ability PLLA high elasticity properties TPU in application minimally invasive surgery for bone tissue engineering. However, easily forms a sea-island-like structure matrix, decreasing properties. In this study, co-continuous phase matrix was constructed by adding Fe3O4 nanoparticles due to changed interfacial tension flow...
