Orlando, September 21, 2022 – A team of University of California researchers in the US has demonstrated the efficacy of a nanomaterials-based disinfectant they developed to combat the spread of the COVID-19 virus. Through their experiments, they found that the disinfectant is able to kill many dangerous viruses including SARS and Zika. The findings of their findings were recently published in Applied Materials and ACS Interfaces.
Udit Kumar, a PhD student at Department of Materials Science and Engineering (MSE) and lead author of the journal article. “Given the topic and potential impact of antiviral research at the moment, our article will certainly help in our fight against global pandemics.”
The paper identifies the most recent study from A A multidisciplinary team of researchers This includes Sudipta Seal, chair of MSE, and Griff Parks, medical school virologist and director Burnett School of Biomedical Sciences. They experimented with nanoscale yttrium silicate, which has antiviral properties that are activated by white light, such as sunlight or LED lights. As long as there is a constant source of light, the antiviral properties regenerate, creating a self-disinfectant for surfaces.
“Yttrium silicate acts as a silent killer, with antiviral properties that are constantly recharged by light,” Kumar says. “It is more effective in reducing the spread of many viruses from surface to surface.”
Kumar says they tested their yttrium silicate on surfaces disinfected with white light with high viral loads in about 30 minutes. In addition, the nanomaterial was able to combat the spread of other viruses including parainfluenza, vesicular stomatitis, rhinovirus, Zika and SARS.
“This disinfection technology is an important achievement for both engineering and health because we have all been affected during the pandemic,” Sell says. “COVID is still going on and who knows what other diseases are on the horizon.”
Other researchers from the University of California, including Medical School Postdoctoral Researcher Candice Fox ’16MS’ 19 Ph.D.nanotechnology student Balashwin Babu 20 Materials science and engineering student Eric Marcelo are co-authors of the paper.
“This publication is the culmination of timely insight by the investigators regarding the importance of rapid development of broad-spectrum antimicrobials, as well as hard work in the laboratory to demonstrate the efficacy of our new materials,” Parks says. “This is an outstanding example of the power of interdisciplinary research – in this case, the materials science and microbiology researchers from CECS and COM.”
The research is funded by the US National Science Foundation’s RAPID Program.
