Abstract:
The COVID-19 pandemic is the worst and largest global public health outbreak of 21st century. According to WHO more than 5 million people have died and 250 million are affected with SARS-CoV-2. One of the major sources of infection is the spreading droplet released by the infected person through cough, exhale, or sneezing. These heavy droplets rapidly fall on different surfaces and live there for some time depending on conditions. The surfaces infected with living viruses is one of the reasons to infect a healthy person. Smart surfaces with contact killing properties can help in slowing down the spread of viruses, are strongly needed. In this study, copper oxide nanoparticles were synthesized by one-pot process and subsequently deposited by dip and dry method onto the surface of fabric. The size of CuO nanoparticles was found 16 ± 1.6 nm from PXRD using Scherrer equation. Also, FE-SEM images shows that CuO nanoparticles aggregate to form ginger like structures (<100 nm) which are uniformly distributed on the surface of fabric. Thus, the smaller size and even distribution of CuO particles yields maximum zone of inhibition for antibacterial as well as antiviral activity. The virucidal activity of CuO nanoparticles treated fabric against adenovirus was found to be 99.99% with comparison to the untreated fabric which shows no reduction in viral litres according to ISO 18184 testing standard. The deposited CuO coating sustained 25 washes without losing activity. The coating can be applied to variety of fabric types and can be widely used in the face mask, clothing, and bedding in hospital settings.
