Researchers at LNLS selected silver nanoparticles of different sizes and evaluated the effect of these nanoparticles on different bacterial strains.
Silver nanoparticles have an antibacterial effect and therefore have potential biomedical applications. Bacteriological tests have revealed that this effect depends on the size of the nanoparticles and the type of microorganism. The challenge consists in performing selective fractionation to identify the most effective nanoparticles for each type of microorganism.
