Proteomics researchers grapple with finding a certain protein in a veritable alphabet soup of others. Now scientists have devised a simple microfluidic method that can pull out specific proteins from a complex mixture (Anal. Chem., DOI: 10.1021/ac200073p).

Microfluidic characterization of proteins appeals to researchers because they can work with small amounts of their precious samples. But isolation of a protein from a sample "is always plaguing microfluidic . . .
