The infections leading to failed implants can be controlled mainly by metal and oxide-based nanoparticles. In this work, the randomly distributed AgNPs-doped onto hydroxyapatite-based surfaces were produced on zirconium micro arc oxidation (MAO) electrochemical deposition processes. characterized XRD, SEM, EDX mapping area contact angle goniometer. MAO surfaces, which is beneficial for bone tissue growth exhibited hydrophilic behaviors. bioactivity of improved compared bare Zr substrate under SBF conditions. Importantly, antimicrobial activity E. coli S. aureus control samples.

The one of main reasons the premature failure Ti-based implants is infections. metal- and metal oxide-based nanoparticles have very high potential on controlling In this work, randomly distributed AgNPs-deposited onto well-ordered TiO2 nanotube surfaces were fabricated titanium by anodic oxidation (AO) electrochemical deposition (ED) processes. surfaces, which beneficial for bone tissue growth exhibited hydrophilic behaviors. Moreover, prevent leaching metallic Ti ions from implant surface, indicated great corrosion resistance under SBF conditions. was improved up to about 145% compared bare Gr2 surface. cell viability improved. Importantly, antibacterial activity Gram-positive Gram-negative bacteria. Eventually, it can be concluded that possess stability long-term usage applications.

Infections continue to pose significant challenges in dentistry, necessitating the development of innovative solutions that can effectively address these issues. This study focuses on creating coatings made from polymethyl methacrylate (PMMA) enriched with zinc oxide-silver composite nanoparticles, layered Ti6Al4V-titanium alloy substrates. The application materials aims create a solution for abutments utilized complete dental implant systems, representing area most susceptible bacterial infections. nanoparticles were synthesized using hydrothermal method, optimized through specific temperature and pressure parameters achieve effective morphologies sizes enhance antibacterial efficacy. layers applied titanium substrate spin coating technique, chosen its advantages compatibility involved. Comprehensive analyses conducted antimicrobial powders, including X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive spectroscopy. Furthermore, PMMA-based incorporating evaluated ensure uniformity homogeneity across surface by IR mapping SBF immersion-SEM analysis. activity samples was demonstrated impressive results against Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, as assessed biofilm modulation studies. biocompatibility validated vitro cell-based assays, which excellent between human preosteoblasts, confirming their potential suitability future use implants.

Clinically, significant challenges remain in the treatment of implant-associated osteomyelitis. Herein, we modified process an active screen plasma surface technique to prepare a silver nanoparticle coating and then performed vitro vivo experiments investigate effectiveness nanoparticle-coated products prepared using this innovative treating Staphylococcus- Pseudomonas aeruginosa-induced Consequently, microstructures, antibacterial properties, corrosion performance, biocompatibility, biosafety materials were evaluated our study. The capacity 2h-Ag-aspsm@SS was investigated microbiological counting assays, bacterial viability biofilm formation observations, expression biofilm, compared antibiotic bone cement nails control groups. Similarly, through micro-CT, cultures, histopathological staining. biocompatibility safety examinations, including blood biochemical tests histology, showed that Ag-aspsm@SS caused no obvious harm body. In summary, study demonstrated could potentially serve as implant for osteomyelitis with long-lasting antimicrobial capacity.
