Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only near-infrared light.
They used fluorescent materials called porphyrins within the surface of a polymersome, a cell-like vesicle, to image a tumor within a living rodent. It should also be possible to use an emissive polymersome vesicle to transport therapeutics directly to a tumor.
The… read more
