Abstract
The disclosure is directed at a system and method for non-microbial prediction of antimicrobial efficacy of an antimicrobial item, such as, a metal surface or materials impregnated with biocidal metal ions or nanoparticles. A test formulation is applied to a surface of interest and a color change of the test formulation is then analyzed and then correlated with antimicrobial activity.
Claims18
A method for non-microbial prediction of antimicrobial efficacy of an antimicrobial item comprising:
- producing a test solution;
- applying the test solution to the antimicrobial item;
- analyzing a color change of the test solution after exposure of the test solution to the antimicrobial item;
- and
- correlating the color change with a level of antimicrobial efficacy.
2 more elements
A test material for use in non-microbial prediction of antimicrobial efficacy of an antimicrobial item comprising:
- a component that changes color when in contact with metal ions leaching from the antimicrobial item or reactive oxygen species on the antimicrobial item.
