Light-activated copper microrobots use single-atom catalysis and peroxide to penetrate biofilms, generate reactive oxygen ...

Concentrating light in a volume as small as the wavelength itself is a challenge that is crucial for numerous applications.

Today's super-resolution microscopes have made it possible to observe the nanoscale world with unprecedented detail. However, they require fluorescent tags, which reveal structural details but provide ...

(Electron microscopes ... reproduction or death. Lately, microscopy has been greatly enhanced by digital image processing. For microscopists as well as ordinary shutterbugs, digital photographs ...

Argonne researchers have shown that they can use light to temporarily alter the crystal symmetry within lead sulfide quantum dots. This process reduces the off-centering of lead atoms and affects the ...
