    A golden – purple – discovery

    As a scientist at 3M, Manjiri was looking for a material that could detect salmonella in food samples. That’s when it happened. During her testing, she realized that a nanoscale gold powder (which is actually purple) killed the microorganisms. She hopes that the powder will be applied to products in countless ways to make settings like hospitals and food prep areas safer.

    “You can have certain unexpected discoveries. Was I screening only for materials that kept bacteria alive? Not necessarily. I kept my horizons open.”
