With a few quick folds of a sheet of photolithographically patterned paper, Hong Liu and Richard M. Crooks of the University of Texas, Austin, have devised a more functional assembly of paper microfluidic devices (J. Am. Chem. Soc., DOI: 10.1021/ja2071779). In years past, George M. Whitesides and coworkers at Harvard University have reported making three-dimensional paper microfluidic devices, which have potential as low-cost medical diagnostic tools. In these devices, microfluidic channels and reservoirs . . .
