NW as gas senor

Our nanowire experts Dr. Lilian Vogl, Dr. Peter Schweizer (now both at EMPA, Thun Switzerland), and Peter Denninger from the Institute of Micro- and Nanostructure Research headed by Prof. Spiecker recently published their work about gold nanowires provided by Gunther Richter from the Max Planck Institute for Intelligent Systems with the title „Sensing capability of single nanowires studied with correlative in situ light and electron microscopy“ in ACS Nano. Congratulations to all the authors!

They have demonstrated that even a single nanowire can be used as a nano-cantilever to sensor devices by analyzing the vibrational resonance under different atmospheric conditions. In order to do so, they developed a compact gas chamber, which enables them to observe the nanowire vibration underneath the light microscope. The correlation of the intrinsic nanowire properties observed within the electron microscope with the extrinsic behavior affected by the atmospheric conditions opens up the opportunity to characterize the application-related functional properties of nano-cantilevers suitable for sensor device applications.
