Microfabrication of ever smaller devices, such as microanalytical systems or microreactors, poses significant technical challenges. Kenis et al. (p. 83; see the cover and the news story by Hellemans) address one challenge, namely, how to pattern the insides of small capillaries in a spatially localized manner. The method exploits the laminar flow properties of multiple liquid streams to induce chemical reactions at the desired place. For example, a thin silver wire was grown in the capillary, as well as a functioning three-electrode system inside an elastomeric channel.
