    • Electrical pulse fabrication of graphene nanopores in electrolyte solution 

      Kuan, Aaron Tzeyang; Lu, Bo; Xie, Ping; Szalay, Tamas; Golovchenko, Jene Andrew (AIP Publishing, 2015)
      Nanopores in graphenemembranes can potentially offer unprecedented spatial resolution for single molecule sensing, but their fabrication has thus far been difficult, poorly scalable, and prone to contamination. We demonstrate ...
    • Intracellular Recordings of Action Potentials by an Extracellular Nanoscale Field-Effect Transistor 

      Duan, Xiaojie; Gao, Ruixuan; Xie, Ping; Cohen-Karni, Tzahi; Qing, Quan; Choe, Hwan Sung; Tian, Bozhi; Jiang, Xiaocheng; Lieber, Charles M. (Nature Publishing Group, 2012)
      The ability to make electrical measurements inside cells has led to many important advances in electrophysiology. The patch clamp technique, in which a glass micropipette filled with electrolyte is inserted into a cell, ...
    • Kinked p–n Junction Nanowire Probes for High Spatial Resolution Sensing and Intracellular Recording 

      Jiang, Zhe; Qing, Quan; Xie, Ping; Gao, Ruixuan; Lieber, Charles M. (American Chemical Society, 2012)
      Semiconductor nanowires and other semiconducting nanoscale materials configured as field-effect transistors have been studied extensively as biological/chemical (bio/chem) sensors. These nanomaterials have demonstrated ...
    • Outside Looking In: Nanotube Transistor Intracellular Sensors 

      Gao, Ruixuan; Strehle, Steffen; Tian, Bozhi; Cohen-Karni, Tzahi; Xie, Ping; Duan, Xiaojie; Qing, Quan; Lieber, Charles M. (American Chemical Society, 2012)
      Nanowire-based field-effect transistors, including devices with planar and three-dimensional configurations, are being actively explored as detectors for extra- and intracellular recording due to their small size and high ...
    • Probing electron transfer mechanisms in Shewanella oneidensis MR-1 using a nanoelectrode platform and single-cell imaging 

      Jiang, X.; Hu, J.; Fitzgerald, L. A.; Biffinger, J. C.; Xie, P; Ringeisen, B. R.; Lieber, Charles M. (Proceedings of the National Academy of Sciences, 2010)
      Microbial fuel cells (MFCs) represent a promising approach for sustainable energy production as they generate electricity directly from metabolism of organic substrates without the need for catalysts. However, the mechanisms ...
    • Sub-10-nm Intracellular Bioelectronic Probes from Nanowire-Nanotube Heterostructures 

      Fu, Tian-Ming; Duan, Xiaojie; Jiang, Zhe; Dai, Xiaochuan; Xie, Ping; Cheng, Zengguang; Lieber, Charles M. (Proceedings of the National Academy of Sciences, 2014)
      The miniaturization of bioelectronic intracellular probes with a wide dynamic frequency range can open up opportunities to study biological structures inaccessible by existing methods in a minimally invasive manner. Here, ...
    • Synthesis and Structure of Solution-Stable One-Dimensional Palladium Wires 

      Campbell, Michael Glenn; Powers, David C.; Raynaud, Jean; Graham, Michael J.; Xie, Ping; Lee, Eunsung; Ritter, Tobias (Nature Publishing Group, 2011)
      One-dimensional metal wires are valuable materials because of their optical and electronic anisotropy, and they have potential utility in devices such as photovoltaic cells and molecular sensors. However, despite more than ...
