Carnegie Mellon enhances Quantum Dot Corp. technology for long-term, live-animal imaging
...o fragile for most biological studies in vivo, the coating
is the most critical step," explained Ballou, research scientist at the Molecular Biosensor and Imaging Center (MBIC) at Carnegie Mellon's Mellon College of Science. "The new coatings allowed us to observe quantum dots much longer than previously dem...
Purdue engineers develop quick, inexpensive method to prototype microchips
...f Chemical Engineers Journal, the team showed that coating
the fibers with materials that attract different types of molecules allowed them to separate specific proteins from a mixed solution. By manipulating the fiber's properties, scientists can identify or separate various types of molecules, such as pro...
Researchers probe how microbes speed up acid production at mining sites
...chemistry: microbes react with the pyrite surface, coating
it with chemicals that would be expected to hinder further reactions. Despite the formation of such coatings, however, microbe-mediated reactions occur tens of thousands of times faster than when no microbes are present. ''That's a puzzle,'' said Alf...
