New UGA Technology Makes Textiles Permanently Germ-free; Targets Healthcare-Associated Infections

"In addition," said Gama, "If for some reason the antimicrobial layer is removed from an article-through abrasion, for example-it can be reapplied by simple spraying."

Other markets for the anti-microbial technology include military apparel and gear, food packaging, plastic furniture, pool toys, medical and dental instrumentation, bandages and plastic items.

Locklin said the antimicrobial was tested against many of the pathogens common in healthcare settings, including staph, strep, E. coli, pseudomonas and acetinobacter. After just a single application, no bacterial growth was observed on the textile samples added to the culture-even after 24 hours at 37 degrees Celsius.

Moreover, in testing, the treatment remained fully active after multiple hot water laundry cycles, demonstrating the antibacterial does not leach out from the textiles even under harsh conditions. "Leaching could hinder the applicability of this technology in certain industrial segments, such as food packaging, toys, IV bags and tubing, for example," said Gama.

Thin films of the new technology also can be used to change other surface properties of both cellulose- and polymer-based materials. "It can change a material's optical properties-color, reflectance, absorbance and iridescence-and make it repel liquids, all without changing other properties of the material," said Gama.

A paper on the new technology was published by Locklin and colleagues online June 21 in ACS Applied Materials & Interfaces, a peer-reviewed journal of the American Chemical Society.
