Nanotech-based electronic noses getting smaller

morphologically encoded nanostructure in contact with array of metal electrodes

Nanowerk describes a recent advance toward the “e-nose” by an international team of researchers. Team member Andrei Kolmakov explains:

Our approach demonstrates the potential of combining bottom-up nanowire fabrication protocols with state-of-the art microfabrication methods to design prospective simple sensing arrays which, in principle, might be scaled down to the size of few micrometers and thus become the smallest analytical instrument…

Time for open source sensing! I’ll be speaking on this Friday at the Open Science Summit which starts tomorrow. Attend in person or watch the webcast. Hope to see you there. (Image: Dr. Kolmakov, Southern Illinois Univ. at Carbondale)  —Christine Peterson
