Zero-valent iron nanoparticles (ZVI NPs) display promising potential in the removal of organic pollutants and heavy metal ions for environmental remediation. However, it is crucial to prevent the oxidation of ZVI NP and control the release of Fe ions under storage and working conditions. In this study, ZVI NPs are encapsulated in single-axial and co-axial carbon nanofibers by electrospinning polyacrylonitrile (PAN)/Fe3+ nanofibrous mats with different structures and then annealing the PAN nanofi...

Weak mechanical properties and mismatching of elastic modulus to human bone restricts the use of PEEK as a bone implant material. By introducing reinforcing particles in polymers, composite material properties could be tailored to meet specific design requirements. In this work, composite materials with PEEK as a matrix and Al2O3 as reinforcing fillers were prepared by an injection molding method. Subsequently, the effects of different particle sizes (30 nm, 0.2 μm, 5 μm) and distinct contents (...

Studies have reported that the incorporation of graphene oxide (GO) and hydroxyapatite (HA) into biocompatible polymers (such as collagen (Col), chitosan, alginate, etc) results in enhanced structural and mechanical properties respectively. The objective of this study was to prepare and characterize three-dimensional (3D) porous Col/GO/HA nanocomposite scaffolds and to investigate cytocompatibility and osteogenic differentiation potential of rat bone marrow mesenchymal stem cells (rBMSCs) on the...

Nanofiber membranes display promising potential in biomedical fields, especially as scaffolds for drug delivery and tissue engineering. The structures and components of nanofibers play crucial roles in improving the mechanical properties and drug-releasing performance of nanofiber membranes. In this work, poly(lactic acid) (PLA)/graphene oxide (GO) nanofiber membranes with different structures (single-axial and co-axial structure) were prepared by electrospinning. The morphologies, structures, a...

In this work, the fluorescent hydroxyapatite nanoparticles (HA NPs) were synthesised by doping cerium (Ce) ions into the crystal structure of HA at different concentrations. The fluorescent property of the Ce-doped HA NPs was determined by the content of Ce doping. The results show that HA NPs with the Ce-doping content of 5% displayed the highest fluorescent emission peak near 380 nm at the excitation wavelength of 300 nm. The CCK-8 assay showed that no significant cytotoxicity was observed whe...

In this work, a novel agarose gel electrophoresis strategy has been developed for separation of DNA fragments by doping graphene oxide (GO) into agarose gel. The results show that the addition of GO into agarose gel significantly improved the separation resolution of DNA fragments by increasing the shift distances of both the single DNA fragments and the adjacent DNA fragments and completely eliminating the background noise derived from the diffusion of the excessive ethidium bromide (EB) dye in...
