Nanoparticles in consumer products significantly alter normal gut bacteria – Nathan Gray

Writing in Environmental Engineering Science, researchers used a model of the human gut to test how exposure to three different nanoparticles (NP) that are commonly used in consumer products – zinc oxide, cerium dioxide, and titanium dioxide – affects the make-up of the bacterial communities in our gut (known as the microbiota). “Understanding the interactions between NPs and bacteria in an …
