Multifunctional Bioactive Coatings Based on Bioglass, Vitamin D3, and Melittin Deposited via MAPLE for Enhanced Osseointegration, Antibacterial Activity, and Corrosion Resistance of Titanium Implants

open access: yesAdvanced Materials Interfaces, EarlyView.
Matrix‐Assisted Pulsed Laser Evaporation (MAPLE) technique is used to cover titanium (Ti) substrates with multifunctional bioactive coatings composed of bioglass, vitamin D3, and melittin. Coatings exhibited excellent chemical integrity and favorable micro/nanostructured morphology (promoting cellular adhesion and viability), and a sustained release of

Cu and Cu‐30Ni Alloy as Anti‐Viral Materials for High‐Touch Surfaces: Efficacy in a Simulated Public Environment with Frequent Cleaning Practices

open access: yesAdvanced Materials Interfaces, EarlyView.
This study evaluates the antiviral efficacy and corrosion behavior of pure copper and Cu‐30Ni alloy on high‐touch surfaces under simulated public conditions with periodic cleaning. Copper shows faster virus inactivation due to higher ion release, while Cu‐30Ni offers better aesthetic durability.

Disruption of Sulfur Metabolism and Redox Homeostasis in Staphylococcus aureus Using Mechanically Robust Antibiofilm Ti‐Bi Alloys

open access: yesAdvanced Materials Interfaces, EarlyView.
Titanium (Ti) and bismuth (Bi) are selected as alloying elements for the preparation of the Ti‐Bi binary alloy system. Biofilm formation is found to be inhibited by bismuth through the disruption of sulfur metabolism and redox homeostasis, as well as through the direct downregulation of biofilm‐associated proteins.
