Antioxidant Activities of Nanomaterials: Mechanisms, Applications, and Technological Potential

Dear Colleagues,

The search for innovative and efficient antioxidant agents represents a cornerstone of modern science, driving advancements in healthcare, food preservation, and materials technology. In this context, nanotechnology has emerged as a revolutionary frontier, offering nanomaterials with unique physicochemical properties that confer remarkable antioxidant capabilities. These properties, which include a high surface-area-to-volume ratio, tunable morphology, and enhanced bioavailability, often surpass those of conventional antioxidants. The exploration of these materials, spanning metallic nanoparticles, carbon-based structures, and polymeric nanocomposites, opens up new avenues for combating oxidative stress-related diseases in humans, animals, and plants, preventing product degradation, and developing smart therapeutic and diagnostic platforms. This Special Issue, "Antioxidant Activities of Nanomaterials: Mechanisms, Applications, and Technological Potential", will showcase cutting-edge research and comprehensive reviews that delve into the fundamental mechanisms behind the antioxidant behavior of nanomaterials. We aim to unravel how their size, shape, surface chemistry, and composition influence free radical scavenging and cellular protection. Furthermore, we encourage submissions that showcase their burgeoning applications across diverse fields, including in nanomedicine for targeted drug delivery, in the agro-industry for enhancing crop resilience, in food science for developing active packaging, and in cosmeceuticals. We invite original research articles and reviews that contribute to a deeper understanding of this dynamic field. Topics of interest include, but are not limited to, the following:

• Novel synthesis and characterization of antioxidant nanomaterials;
• In vitro and in vivo studies elucidating antioxidant mechanisms and efficacy;
• The computational and theoretical modeling of nano-antioxidant interactions;
• Applications in biomedicine (e.g., neuroprotection, anti-inflammatory therapies, regenerative medicine);
• Technological applications in food safety, agriculture, and industrial coatings;
• Assessments of biocompatibility, toxicology, and long-term environmental impacts.

By bringing together multidisciplinary expertise, this Special Issue will serve as a valuable resource for researchers and engineers, fostering future innovation and highlighting the immense technological potential of nano-antioxidants.
