Tiny tango: Device sorts microscopic particles with speed and precision
...uang said the device could also result in improved ink
jet printers, which produce better results if the ink
particles are sized precisely. The researchers are now working to make a tango array for e...

UCSD scientists develop novel way to screen molecules
...they wanted to attach to this surface to the empty ink
wells of an inkjet printer cartridge and used the printer to "print" the molecules onto the CD. This resulted in a CD with molecules bound to its readable surface in specific locations relative to the pits in the metal layer of the CD encoding the d...
