Zinc Dioxide Zinc Peroxide (ZnO2) is a compound possessing very strong oxidizing properties and the ability to generate free radicals and other reactive oxygen species. Nowadays, the material is mainly used in bulk in many areas like rubber and polymer industry, cosmetics, pyrotechnics, or organic synthesis. Nanoxo new patent-pending technology offers a broad range of products based on high-quality zinc peroxide nanoparticles with an average diameter below 5 nm and rationally designed and well-specified characteristics. Nanoxo zinc peroxide (ZnO2) nanostructures are superior to other products available on the market. The small size and well-defined structure of nanoparticles offers considerably better performance and high stability in many potential applications like: - Plastics processing - Material engineering (e.g. antibacterial additives) - Pyrotechnics mixtures - Photocatalyst - Cosmetics - Medicine (e.g. anticancer, wound healing, antibacterial agent) - Electronics - Zinc oxide precursor - Basic scientific research of new nanomaterials The novel organometallic approach developed by Nanoxo enables the manufacturing of tailored products that possess unique properties: - Heavy-metal free composition - Very high purity (electronic purity on request) - Monodispersed nanoparticles with typical average size between 1-5 nm - Possibility of custom functionalization - Hydrophilic or hydrophobic - Long term stability (100% ZnO2 content) - High specific surface area - Scalability High flexibility of the technology allows to improve end-user processes and products by rational design of new materials adapted to specific requirements.

NANOXO Zinc Oxide quantum dots (ZnO QDs) are of unprecedented quality. They have significantly better chemical and physical properties than their counterparts currently being produced by the most popular sol-gel method. Organometallic approach The organometallic approach developed by Nanoxo allows for manufacturing defect-free ZnO QDs with novel physicochemical properties such as long-term stability, monodispersity, a relatively high quantum efficiency, record-long luminescence lifetimes and EPR silence under standard conditions. The unique features of the tightly coordinated and impermeable organic shells stabilizing the surface make the new ZnO quantum dots resistant to both chemical and biological environments - True, non-toxic, bio-safe - UV absorption up to 400 nm (depending on product version) - Luminescence lifetime up to µseconds - Tunable color emission (480 – 570 nm) - High quantum yield and brightness - Size tunable (2 – 10 nm) - Possibility of attaching custom chemical groups for further coupling (click chemistry) - Hydrophilic or hydrophobic (dependent on product version) - Long term stability - Do not aggregate into clusters - Different shapes - Scalability Nanoxo novel Zinc Oxide Quantum Dots are available at https://nanoxo.eu/shop/ For customized solutions - ZnO Qdots in various solvents, polymers, paints or varnishes, or for special applications please inquire at: company@nanoxo.eu
