Tiny tango: Device sorts microscopic particles with speed and precision
...g completely predetermined paths, like pennies and dimes rolling through a child's coin sorter. Previous attempts required the particles to diffuse randomly so that bigger particles slowly drifted one way and smaller ones another. Researchers had believed that fixed paths were not possible in part because ...... be around 2 to 3 mm - about thethickness of three dimes stacked on top of each other. The INEEL and BNFL havebeen collaborating on this technology since 1995, and ultimately hope to use itto clean up radioactively contaminated concrete at nuclear facilities worldwide. Before the microbes create the su...
