This groundbreaking study presents a novel method for precise, nanoscale control over the release of reactive oxygen species (ROS) - highly promising agents for combating antimicrobial resistance, environmental contamination, and more.

By combining plasma-deposited AgOx-TiOx catalytic thin films with tunable nanoporous SiOx-like surface coatings, the team achieved selective delivery of specific ROS (like superoxide and singlet oxygen), all without ion leaching, at room temperature, and even in the dark. This marks a major advancement in the development of safe, sustainable antimicrobial and antiviral surfaces.

A special thank you goes to the fantastic team at NOVA, whose expertise and collaboration were instrumental in making this research a success. Their contribution highlights how interdisciplinary cooperation can lead to impactful scientific innovation.

We are proud of this achievement and look forward to further discussions on the potential applications of this technology across biomedicine, environmental safety, and materials science.
