New metalloprotein tool. 589 A Science Tailing of peaks. Researchers have long complained about it, yet peak tailing in reversed-phase separations of organic cations remains a problem. Mary Wirth, Melody Ludes, and Derrick Swinton of the University of Delaware use single-molecule spectroscopy and atomic force microscopy to better understand the causes. QCMs in multiples.
Microchip gets a tip.
That is not so simple. Iulia Lazar, Rose Ramsey, and Mike Ramsey at Oak Ridge National Laboratory and Steve Sundberg from Caliper Technologies created a microchip with a nanoelectrospray tip for high-sensitivity analysis. Getting the measure of polymers. Imagine sequencing a polymer like polyethylene glycol as if it were a protein. A News from BioMEMS Living chips.
