Antimicrobial coatings systems take advantage of this by including photocatalytically active compounds in their formulations (i.e. titanium dioxide) that cause the coating to “flake” off over time. [26] These flakes carry the microbes along with them, leaving a “clean” coating behind. Systems like this are often described to be self ...
“Ants have palates, and if they don’t take the bait immediately, you’ll need to try a different formula,” says Suiter. “It’s not like they’re going to change their minds.”
One way to compare disinfectants is to compare how well they do against a known disinfectant and rate them accordingly. Phenol is the standard, and the corresponding rating system is called the "Phenol coefficient". The disinfectant to be tested is compared with phenol on a standard microbe (usually Salmonella typhi or Staphylococcus aureus ...
