    • Correlative light and electron microscopy using cathodoluminescence from nanoparticles with distinguishable colours 

      Glenn, David R.; Zhang, Huidan; Kasthuri, Narayanan; Schalek, Richard L.; Lo, P. K.; Trifonov, Alexei; Park, Hongkun; Lichtman, Jeff; Walsworth, Ronald L. (Nature Publishing Group, 2012)
      Correlative light and electron microscopy promises to combine molecular specificity with nanoscale imaging resolution. However, there are substantial technical challenges including reliable co-registration of optical and ...
    • A Genetic Strategy for Probing the Functional Diversity of Magnetosome Formation 

      Rahn-Lee, Lilah; Byrne, Meghan E.; Zhang, Manjing; Le Sage, David; Glenn, David R.; Milbourne, Timothy; Walsworth, Ronald L.; Vali, Hojatollah; Komeili, Arash (Public Library of Science, 2015)
      Model genetic systems are invaluable, but limit us to understanding only a few organisms in detail, missing the variations in biological processes that are performed by related organisms. One such diverse process is the ...
    • High-Flux Beam Source for Cold, Slow Atoms or Molecules 

      Maxwell, S. E.; Brahms, N.; deCarvalho, R.; Glenn, David R.; Helton, J. S.; Nguyen, S. V.; Patterson, D.; Petricka, J.; DeMille, D.; Doyle, John M. (American Physical Society (APS), 2005)
      We demonstrate and characterize a high-flux beam source for cold, slow atoms or molecules. The desired species is vaporized using laser ablation, then cooled by thermalization in a cryogenic cell of buffer gas. The beam ...
    • Limits to Resolution of CW STED Microscopy 

      Trifonov, Alexei; Jaskula, Jean-Christophe; Teulon, Claire; Glenn, David R.; Bar-Gill, Nir; Walsworth, Ronald Lee (Academic Press (Elsevier BV), 2013)
      We report a systematic theoretical and experimental study of the limits to spatial resolution for stimulated emission depletion (STED) superresolution fluorescence microscopy using continuous wave (CW) laser beams. We ...
    • Magnetic Field Imaging with Nitrogen-Vacancy Ensembles 

      Pham, Linh My; Le Sage, David Anthony; Stanwix, Paul L.; Yeung, Tsun Kwan; Glenn, David R.; Trifonov, Alexei; Cappellaro, Paola; Hemmer, Philip; Lukin, Mikhail D.; Park, Hongkun; Yacoby, Amir; Walsworth, Ronald L. (Institute of Physics, 2011)
      We demonstrate a method of imaging spatially varying magnetic fields using a thin layer of nitrogen-vacancy (NV) centers at the surface of a diamond chip. Fluorescence emitted by the two-dimensional NV ensemble is detected ...
    • Optical magnetic detection of single-neuron action potentials using quantum defects in diamond 

      Barry, John F.; Turner, Matthew James; Schloss, Jennifer M.; Glenn, David R.; Song, Yuyu; Lukin, Mikhail D.; Park, Hongkun; Walsworth, Ronald Lee (Proceedings of the National Academy of Sciences, 2016)
      Magnetic fields from neuronal action potentials (APs) pass largely unperturbed through biological tissue, allowing magnetic measurements of AP dynamics to be performed extracellularly or even outside intact organisms. To ...
