Summary: Silicon nitride nanowires-pyrolytic carbon-hydroxyapatite-carbon matrix (Si3N4nws@PyCnls-HA-C) composites with multilayer core-shell structures were synthesized by chemical vapor deposition (CVD), pulsed electrodeposition (PED), and chemical vapor infiltration (CVI) methods. The microstructure, in-vitro bioactivity, and in-vivo histocompatibility of Si3N4nw-s@PyCnls-HA-C (SPHC) composites were evaluated. In vitro, the SPHC exhibited a cell proliferation rate of 157.7% and demonstrated outstanding protein adsorption. In vivo, the SPHC demonstrated excellent histocompatibility. Therefore, the SPHC composites can serve as an alternative suitable biomaterial for bone tissue engineering.

Summary: In this study, rare earth Europium (Eu3+) complexes were successfully grafted onto carbon fibers, imparting them with fluorescence characteristics. The Eu-complex grafted carbon fibers (CEuCF) exhibited sharp red emission attributed to the 5D0-*7F1 and 5D0-*7F2 transitions of Eu3+. The surface roughness of the carbon fibers changed after the introduction of fluorescence properties. The fluorescence intensity of the carbon fibers increased initially and then decreased with increasing Eu content, reaching its peak at a molar ratio of 2 mmol. The energy transfer in the CEuCF was also discussed in detail. Enduing carbon fibers with luminescent properties could expand their application areas.

Summary: Sisal fibers were used to prepare composite Co/Co2N/N/C catalysts by high-temperature pyrolysis and precise control of the composite proportion of SPC and CoPc. The SPC@CoPc-1-4 catalyst showed high Eonset potential (1.04 V), high stability (90.50%), and slightly lower E1/2 (5 mV) compared to Pt/C catalyst. These composite catalysts combining biomass carbon materials and phthalocyanine series will provide a valuable reference for non-precious metal ORR catalysts.

Summary: In this study, a nanoplatform decorated with Pt and Au nanoparticles loaded with indocyanine green was developed for precise photodynamic therapy (PDT) and microenvironment improvement in choroidal neovascularization (CNV) treatment. The nanoplatform could penetrate the internal limiting membrane and target CNV, while Pt nanoparticles acted as catalase-like agents to relieve hypoxia and enhance PDT, and Au nanoparticles showed anti-inflammatory and anti-angiogenesis properties. Compared to verteporfin treatment, the nanoplatform significantly downregulated the mRNA expressions of hypoxia-inducible factor-1 alpha and VEGF, achieving a comprehensive CNV treatment effect.
