Summary: This study developed three chitosan (CS)-based porous scaffolds, including CS, CS/CNT (carbon nanotubes), and CS/CNT/HA (nano-hydroxyapatite), which exhibited high swelling ratio, excellent antibacterial activity, outstanding cytocompatibility, and blood compatibility in vitro. The introduction of CNTs significantly improved the mechanical properties and displayed excellent photothermal response, resulting in superior wound healing performance compared to CS scaffolds in a mouse full-thickness skin wound model. The CS/CNT/HA composite scaffold showed the strongest ability to promote full-thickness cutaneous wound closure and skin regeneration, attributed to the synergistic effect of photothermal response from CNT and excellent bioactivity from n-HA.

Summary: The hybrid alginate-Au nanoparticle films were prepared by electrophoretic deposition, which was caused by the localized pH drop at the electrode surface due to the oxidation of hydroquinone (HQ) catalyzed by citrate-coated gold nanoparticles (cit-Au NPs) with different diameters. The EPD of alginate occurred at different voltages depending on the size of the cit-Au NPs and the presence of cit-Au NPs resulted in higher catalytic activity for the oxidation of HQ. The post-treatment with Ca2+ solution led to the formation of hybrid Ca-Alg-Au NP hydrogel films.

Summary: The study reinforced modified multi-walled carbon nanotubes and hydroxyapatite nanorods into polypropylene using a melt compounding approach to create biocomposites of varying compositions with improved mechanical, thermal, and biocompatibility properties. The addition of modified multi-walled carbon nanotubes was found to enhance tensile strength but decrease Young's modulus of the nanocomposites, while both fillers improved thermal and dimensional stability of polypropylene. These nanocomposites show promise for orthopedic applications, particularly in human subchondral bone and lightweight implant fabrication.

Summary: The in situ growth of tunable gold nanoparticles on titania nanotubes guided by TiNTs was realized by electrodeposition to modulate macrophages polarization, thus improving osteogenesis. The deposition of Au on different surfaces induced different macrophage polarizations, affecting osteoblastic differentiation, and the in vivo tests confirmed the effectiveness of Au@10VNTs in bone formation and macrophage infiltration. Cytokine analysis revealed the upregulation of pro-healing cytokines and downregulation of pro-inflammatory cytokines, along with significant inhibition of the NF-kappa B pathway.
