Tiny particles embedded with light-emitting molecules have allowed researchers to “see” a tumor below the skin.

Researchers at the University of Pennsylvania and the University of Minnesota developed the cancer imaging system by embedding fluorescent materials called fluorophores into cell-like sacs called polymersomes.

The research shows that the glowing nanoparticles can be used to image tissue structures deep below the skin, says researcher Michael Therien of Penn.

“It should also be possible to use an emissive polymersome vesicle to transport therapeutics directly to a tumor,” says Therien, “enabling us to actually see if chemotherapy is really going to its intended target.”
