A new “killer” paint will reach hospitals to eliminate potentially fatal bacteria for immunocompromised patients. This mechanism will be able to eliminate bacteria harmful to the minimum contact.
There are several bacteria in hospitals, which cause fatal infections. Now, a new ink can help prevent this from happening, quickly kill any microbes.
This is not the first time we see a germicide coating For door handles, handrails, benches and other non -porous surfaces in hospitals. These coatings use antimicrobial ingredients, including silver, copper and gold.
But the ink presented in a study this Wednesday in Nature It’s different. AND more lasting, more effective and cheaper.
Developed in partnership with the British Company Indestructable Paint, the coating consists of the company’s conventional transparent bright resin, along with a 2% concentration of a broad spectrum biocide agent known as chlorhexidine diglucanate (CHX).
As detailed A, these two ingredients were combined, left to react to each other for 15 minutes, then painted on steel samples and cured at a temperature of 60 ° C (140 ºF) for 90 minutes.
Then droplets of bacterial solutions of Staphylococcus aureus, They exhibited chill e Pseudomonas aeruginosa They were applied to the ink and left to dry at room temperature for 18 hours. This action has simulated the way a painted surface can be sprinkled in a hospital.
Completely eradicated bacteria
When the samples were later tested, it was found that the three types of bacteria had been completely eradicated.
As scientists at the University of Nottingham explained, CMX has achieved this done through the generation of reactive oxygen species that broke the external protective membranes of the microbes. For reference, previous studies have shown that the S. aureus and E. coli can survive on stainless steel surfaces for up to six and four weeksrespectively.
“It is crucial that technologies, such as this antimicrobial paint, are developed to prevent the propagation of pathogenic microorganisms to vulnerable patients and face the increasing threat of antimicrobial resistance, ”said the investigation leader, Felicity of Coganem .
