Innovative Antimicrobial Coating Developed in Canada

October 26, 2023

Researchers at the University of Windsor in Ontario, Canada, have developed a novel antimicrobial coating, according to European Cleaning Journal (ECJ). Composed of ionic fluids and copper nanoparticles, the coating is designed for application on frequently touched surfaces, potentially offering a longer-lasting, germ-free state than traditional cleaning methods.

As stated by the University of Windsor research team, “The problem with conventional sanitization techniques is that it’s not a one-and-done kind of thing,” highlighting the need for constant reapplication and the risk of material damage associated with current cleaning practices. This new coating aims to provide a more durable and straightforward solution, utilizing copper’s natural germicidal properties.

Sima Dehghandokht, one of the researchers, said that the use of the new coating could go beyond its initial scope of doorknobs and handrails. “[Uses] could also include hospitals, greenhouses, agri-food production facilities and even scientific labs, where we deal with pathogens and harmful bacteria all the time,” she explained.

According to ECJ, further research is needed to assess the compound’s toxicity and length of effectiveness. The team also plans to explore if altering the nanoparticles could extend the coating’s antimicrobial properties and combat more resilient bacteria.
