  1. pmc Single-shot full-field reflection phase microscopy
    Zahid Yaqoob
    G R Harrison Spectroscopy Laboratory, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA
    Opt Express 19:7587-95. 2011
    ..We have measured the path-length sensitivity of our instrument to be approximately 21 picometers/Hz that makes it suitable for nanometer-scale full-field measurement of membrane dynamics in live cells...
  2. pmc Quantitative DIC microscopy using an off-axis self-interference approach
    Dan Fu
    G R Harrison Spectroscopy Laboratory, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA
    Opt Lett 35:2370-2. 2010
    ..This method is practically simple to implement on any standard microscope without stringent requirements on polarization optics. Optical sectioning can be obtained through enlarged illumination NA...

    Yongjin Sung
    G R Harrison Spectroscopy Laboratory, Massachusetts Institute of Technology, Cambridge, MA 02139
    Proc Natl Acad Sci U S A 110:16687-92. 2013
    ..In attached epithelial cells, we find that due to the asymmetry in cell division and size-dependent growth rate, there is active regulation of cell size. Thus, like nonadherent cells, size homeostasis requires feedback control. ..
