Silver Nanoparticles can Kill Yeast



Silver nanoparticles kill yeast that produce oral infections, according to scientists.

The infections are caused by Candida albicans and Candida glabrata. Older people, children and those with immune system problems are more susceptible to the infections. The nanoparticles will soon be tested in mouthwash and dentures to see if the results can be duplicated.

The research was led by Professor Mariana Henriques from the University of Minho and was published in the journal Letters in Applied Microbiology. The research team analyzed the nanoparticles to pinpoint the antifungal properties against the Candida albicans and Candida glabrata. These yeasts cause oral thrush and stomach problems, problems that impact about 70 percent of denture wearers.

To compile the data, the researchers utilized artificial biofilms in situations that closely resembled the conditions of saliva. They added different amounts of the silver nanoparticles and different sizes and there was no change in the effectiveness of their ability to kill the yeast. The nanoparticles can be used in various applications.

There are some concerns about the safety of the nanoparticles but the research team stresses that the information is still in its early stages.

These nanoparticles could eventually be implemented into dentures.
