1/n I was a bit disappointed when I saw this press note from our institute. It starts with an introduction about antibiotic resistance and then goes on to describe silver nanoparticles killing bacteria in a dish. With no tests on mammalian cells. https://ichf.edu.pl/en/press/silver-nanoparticles-guaranteeing-antimicrobial-safe-tea The press note is written by a friend of mine who usually writes very well. But to be fair to Magda, the antibiotics intro is even more prominent in the paper. But so many things kill bacteria that it’s a pointless comparison.
