Quantum Dots Carry Light into Remote Biological Regions Visualizing an object can go a long way toward understanding how it works. For growing numbers of researchers, quantum dots are becoming the tool of choice to provide the necessary light. The semiconductor nanocrystals increasingly are being used as tiny flashlights to illuminate intricate biological phenomena. The images, captured with highly sensitive cameras, are generating fresh ideas and...

Microscopic barrels, bullets and worms of plastic Molded, stretched or extruded into shape, polymeric materials make up items from microscope knobs to culture plates. Increasingly, shaped polymers are playing a role at the micro- and nanoscale as well. But controlling the appearance of structures of this size can prove daunting, as few methods exist to finely manipulate plastic substances into predictable and reproducible forms. Extensively...
