Nanomaterials are being used in medicine, manufacturing and consumer products, but their effects on organisms and the environment are not well understood because of the difficulty in detecting them. Here dual‐energy X‐ray K ‐edge subtraction was used to track two‐dimensional yttrium oxide nanoparticles (which can be found in such household objects as color televisions) in adult mealworms ( Tenebrio molitor ). The insects ingested nanoparticle‐infused feed for different time periods, up to 24 h, and the nanoparticles could then be identified at several locations in the insects' head, thorax and abdomen, mostly within the digestive tract. In time, all particles were excreted.
