A Weapon Against Implant-Associated Infections: Antibacterial and Antibiofilm Potential of Biomaterials with Titanium Nitride and Titanium Nitride-Silver Nanoparticle Electrophoretic Deposition Coatings

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(4), P. 1646 - 1646

Published: Feb. 14, 2025

Implant-associated infections are a frequent complication of surgeries involving biomaterial implants. Staphylococcus and Enterococcus species the leading causes linked to bone-anchored joint To address this challenge, developing antibacterial coatings prevent bacterial attachment biofilm formation on biomaterials is critical. This study aimed evaluate antibiofilm properties two coatings: titanium nitride (TiN) with silver nanoparticles (TiN/Ag). Antibacterial activity was tested against common biofilm-forming pathogens, including Escherichia coli, aureus, faecalis, faecium. The results demonstrated that both significantly reduced cell counts, TiN/Ag coating showing superior performance due addition nanoparticles. enhancement particularly effective in reducing across all strains, most pronounced effects observed for E. faecium faecalis. synergistically improved TiN coating, efficiently disrupting integrity adhesion. By surfaces, offer promising strategy minimize complications associated These findings highlight potential medical applications.

New Antimicrobial Materials Based on Plasticized Polyvinyl Chloride for Urinary Catheters: Preparation and Testing

Polymers, Journal Year: 2024, Volume and Issue: 16(21), P. 3028 - 3028

Published: Oct. 29, 2024

Given the constant increased number of nosocomial infections in hospitals, especially associated with prolonged usage inserted medical devices, our work aims to ameliorate clinical experience and promote faster healing patients undergoing urinary catheterization by improving properties devices materials. Within this research, nine different composites were prepared based on polyvinyl chloride, using three plasticizers (di-(2-ethylhexyl) phthalate, Proviplast 2646, 2755), two antimicrobial additives containing silver nanoparticles. The materials analyzed, their physicochemical determined: water absorption, relative density, plasticizer migration, hydrophobicity/hydrophilicity contact angle measurement, Shore A hardness, tensile strength, elongation at break. Structure morphology also investigated means FTIR, SEM, EDX analyses, thermal (TG-DSC) biological evaluated. most important aspects obtained results are showing that migration was significantly reduced (to almost zero) improved materials’ biocompatibility. Thus, concluded favorable properties, can be further used for catheter development. Pressure–flow studies sizes configurations next steps toward advanced vivo trials.
