High-tech Probes Sneak Inside Your Cells
The newest generation of nano-sized probes should give scientists a look into the secret lives of nuclei within your body, researchers say.
The tiny probes, called quantum dots, are a melding of biology and technology. The crystalline semiconductors with a biological protein coating are no larger than a few hundred atoms. Importantly, they shine brilliantly when hit with a laser.
