Toxic Nanoparticles Coated with Antibiotics Safely Kill Drug Resistant Bacteria

July 11th, 2017 Editors Medicine, Nanomedicine A team of Brazilian scientists may have come up with a practical way of killing off resistant bacteria by targeting them with toxic silver-silica nanoparticles coated with an antibiotic. Since antibiotics don’t have the full punch to eliminate bacteria resistant to them, the researchers instead used the antibiotic ampicillin as a mechanism to deliver

Nanoparticles coated with antibiotic eliminate drug-resistant bacteria

A new strategy to combat antibiotic-resistant bacteria has been described by Brazilian researchers in Scientific Reports, an online journal owned by Springer Nature.

Article Description

The rational synthesis of alternative materials is highly demanding due to the outbreak of infectious diseases and resistance to antibiotics. Herein, we report a tailored nanoantibiotic synthesis protocol where the antibiotic binding was optimized on the silver-silica core-shell nanoparticles surface to maximize biological responses. The obtained silver nanoparticles coated with mesoporous silica functionalized with ampicillin presented remarkable antimicrobial effects against susceptible and antibiotic-resistant Escherichia coli. In addition, these structures were not cell-death inducers and different steps of the mitotic cell cycle (prophase, anaphase and metaphase) were clearly identified. The superior biological results were attributed to a proper and tailored synthesis strategy.
