Bacteria (IMAGE) University of Minnesota Caption In this microscopic image, bacteria shown on the left became extremely elongated upon chronic exposure to nanomaterials used to make lithium ion batteries, illustrating that their biochemical state was significantly altered. Bacteria on the right that have not been exposed to these nanomaterials are typically shaped like short rods.
