Quantum dots get a second chance to shine
A new look at colorful semiconductor particles for visualizing living cells
DAZZLING DOTS Tiny semiconductor particles called quantum dots light up mouse intestines in this microscope image. Red and green represent proteins illuminated by fluorescing quantum dots. Cell nuclei are stained blue with a traditional dye not involving quantum dots.
