Summary: Titanium alloys are commonly used for bone implants due to their high biocompatibility and chemical stability. However, their ability to resist bacteria adhesion and biofilm formation is limited. In this study, a nanocomposite coating made of TiAlVN(Ag)x was deposited on the titanium alloy substrates using magnetron sputtering technique. The coated substrates exhibited significant bactericidal effect without affecting their hardness and cell viability. The coatings showed high inhibition against Pseudomonas aeruginosa bacteria and good compatibility with human osteoblasts.

Summary: This study investigated the characteristics of nanocrystalline diamond films synthesized at low surface temperature on Ti-6Al-4V substrates for biomedical applications. The surface roughness of the substrates was varied by different polishing grits. Regardless of the polishing protocol, nanocrystalline diamond coatings with comparable morphology and purity to those on silicon substrates were achieved. However, the polishing protocol significantly affected the roughness and hardness of the films, with the finest polishing grit leading to increased hardness values.

Summary: Bioorthogonal metallocatalysis allows for nonenzymatic catalytic transformations in living environments. However, most metals are deactivated by reactive biomolecules inside cells, limiting their catalytic activity. In this study, cytocompatible alloyed AuPd nanoparticles were developed for efficient bioorthogonal depropargylations in biological media. Encapsulation of the nanoparticles in mesoporous silica nanorods or a biodegradable PLGA matrix enhanced their intracellular catalytic performance and enabled the release of anticancer drug paclitaxel inside cancer cells. This work demonstrates the potential of nanoalloy encapsulation for mediating new-to-life reactions in cells.

Summary: Compared to parenteral administration, direct pulmonary administration of colistin maximizes lung drug deposition and reduces systemic side effects. However, the current method of aerosolizing the prodrug colistin methanesulfonate (CMS) results in slow conversion to colistin, limiting its effectiveness. This study synthesized nanoparticle carriers loaded with colistin using different techniques, finding that nanoprecipitation of pure colistin showed the highest drug loading and had the potential to reach the entire lung.

Summary: In this study, inorganic nanocatalysts were used to target and deplete glucose and glutathione, key biomolecules for tumor cells, and generate reactive oxidative species, representing a novel and promising strategy against cancer. A ternary assembled nanohybrid based on Au and CuFe2O4 was developed to simultaneously deplete glucose and glutathione and generate reactive oxidative species. This hybrid heterostructure maintained the glucose oxidase-like activity of Au and prevented its deactivation in the presence of glutathione, presenting a promising alternative for potential anticancer therapy within the tumor microenvironment.
