Colloidal Phenol-Amine Coating on Implants for Improved Anti-Inflammation and Osteogenesis

“…The histocompatibility and osteogenic effect of coated samples were assessed in vivo by collecting samples from rats 28 days after the surgery. The one-month time point (28 or 30 days) corresponds to the mid-phase of tissue healing or chronic inflammatory response, wherein a significant difference in the thickness of the fibrous capsule between experimental and control samples can be observed. − The results of our previous study also indicated that the collection of samples at 28 days postoperation is appropriate for obtaining comparable outcomes . In order to explore the regulation of inflammation and biocompatibility in vivo, we measured the thickness of the fibrous capsules of titanium sheets to observe the intensity of the inflammatory response.…”

The HE-stained sections showed that the control group had a thicker fibrous capsule and more severe fibroid changes, while the CT-C group exhibited lighter inflammation (Figure 4A).…”

Ag and MoO3 Nanoparticle-Containing Polyacrylonitrile Nanofiber Membranes for Wound Dressings

“…The observed inhibition zones indicate the effectiveness of the Ag-MoO 3 /PAN nanofibers in inhibiting the growth of both Escherichia coli and Bacillus subtilis bacteria. The NaOH-treated NFM possibly increased the surface roughening and porosity of the composite, which can enhance the contact between the material and the bacteria . The alkaline nature might also support the exposure of more active sites on the surface, which also promotes the release of silver ions, as observed in silver release behavior.…”

“…The NaOH-treated NFM possibly increased the surface roughening and porosity of the composite, which can enhance the contact between the material and the bacteria. 41 The alkaline nature might also support the exposure of more active sites on the surface, 42 which also promotes the release of silver ions, as observed in silver release behavior. The NaBH 4 reducing agent might lead to the reduction of silver ions to metallic silver nanoparticles on the composite's surface, which was confirmed with an XRD pattern.…”
