Researchers are exploring the earthworm as a biological environment for creating CdTe quantum dots, substances that can function as medical imaging agents. The dots are capable of absorbing UV light and fluorescing in the green area of the spectrum. Tests involving cancer cells in a culture dish showed the cells were able to absorb the quantum dots and glow green following exposure to UV light, according to the study published in Nature Nanotechnology. The researchers said there is a need to develop a storage system that will allow the dots to be more effective for a longer period of time.
