Cotton textiles are ubiquitous in daily lifestyle, and they are also one of the primary mediums for transmitting viruses and microbes. Typical techniques to fabricating antiviral and antibacterial textiles generally load the practical additives onto the surface area of the material and/or on to their microfibers. Having said that, this kind of modifications are prone to deterioration right after extensive-time period use thanks to leaching of the additives.
Not too long ago, a transdisciplinary and multi-institutional analysis staff led by Liangbing Hu, Herbert Rabin Distinguished Professor of Supplies Science and Engineering (MSE) at the University of Maryland (UMD) and director of the Middle for Products Innovation (CMI), and William Bentley, Fischell Distinguished Chair in Engineering and director of UMD’s Robert E. Fischell Institute for Biomedical Equipment, and Robert M. Briber, Professor of Materials Science and Engineering and Associate Dean for Study, designed a new antimicrobial cotton textile with Cu ions included into the cotton structure at the molecular stage (Cu-textile), which utilizes the powerful coordination bonding among Cu ions and the cellulose molecules and shows antiviral, antibacterial, wearable, and washable qualities.
This study was posted in Nature Nanotechnology on December 30, 2022.
The Cu-textile shows substantial antiviral and antibacterial overall performance in opposition to the Tobacco mosaic virus (TMV) and Influenza A virus (IAV), as effectively as E. coli, S. typhimurium, P. aeruginosa, and B. subtilis microbes.
