    It’s a Small World After All
    Nanomaterials are types of matter that lie in size between single molecules and bacteria, or approximately one millionth of a millimeter. Where do you find such tiny little objects? Right in plain sight! Maybe you were hungry today and grabbed a slice of American Cheese or a tub of Greek yogurt from the fridge. Maybe afterward you brushed your teeth with toothpaste, or freshened your breath with gum. Maybe you took a shower and used a dandruff shampoo, then put on deodorant. Maybe you then put on stain-resistant pants, dabbed on a little sunscreen, and headed off to campus. All of those items I just mentioned contain nanoparticles, so small you can’t see each one, but essential for product performance.

    In this follow-up to my 2016 TEDxUM talk, I will describe what the nanoparticles do in these products, then talk a little about nanoengineering using DNA, with a particular focus on the future of nanomedicine. Like in the movie “Fantastic Voyage,” nanomedicine is close to being reality.
