Antipathogenic filtration media developed using copper oxide nano ink

Copper oxide (CuO) nanoparticles functionalised using amino acids, were prepared and formulated into an effective antipathogenic ink. Following successful incorporation of the developed ink into disposable face masks for the prevention of respiratory infections, we demonstrate here the successful development and incorpration of the CuO nanoparticle ink into HVAC filter media. The nano ink was applied and cured on polyester and polypropelyne HVAC filtration material and evaluated for antiviral and antipathogenic performance. At least a 90% reduction was found in influenza and SARSCoV2 viruses after 2 hours treatment and at least 99% reduction was found in Pseudomonas aeruginosa Acinetobacter buamannii and Escherichia coli after 18 hours treatment.
The medicinal properties of copper has been well established and have been used since the time of the Egyptian empire. Current uses of copper include hospital touch surfaces e.g. bed frames and door handles, due to copper oxide having unique electrical properties allowing biomedical and antipathogenic properties. Copper nanoparticles were used during both the Swine flu and Bird flu outbreaks and, more recently, have been used to combat the SARSCoV-19 pandemic. Herein we report an optimised synthesis of copper nanoparticles and their functionalisation of filtration devices, including the antiviral and antimicrobial properties…
