    • A method for atomic force microscopy cantilever stiffness calibration under heavy fluid loading 

      Kennedy, Scott J; Cole, Daniel G; Clark, Robert L (2009)
      This work presents a method for force calibration of rectangular atomic force microscopy (AFM) microcantilevers under heavy fluid loading. Theoretical modeling of the thermal response of microcantilevers is discussed including ...
    • A versatile diffractive maskless lithography for single-shot and serial microfabrication. 

      Jenness, Nathan J; Hill, Ryan T; Hucknall, Angus; Chilkoti, Ashutosh; Clark, Robert L (Opt Express, 2010-05-24)
      We demonstrate a diffractive maskless lithographic system that is capable of rapidly performing both serial and single-shot micropatterning. Utilizing the diffractive properties of phase holograms displayed on a spatial ...
    • Electrosprayed core-shell microspheres for protein delivery. 

      Wu, Yiquan; Liao, I-Chien; Kennedy, Scott J; Du, Jinzhi; Wang, Jun; Leong, Kam W; Clark, Robert L (Chem Commun (Camb), 2010-07-14)
      This communication describes a single-step electrospraying technique that generates core-shell microspheres (CSMs) with encapsulated protein as the core and an amphiphilic biodegradable polymer as the shell. The protein ...
    • Inkless microcontact printing on SAMs of Boc- and TBS-protected thiols. 

      Shestopalov, Alexander A; Clark, Robert L; Toone, Eric J (Nano Lett, 2010-01)
      We report a new inkless catalytic muCP technique that achieves accurate, fast, and complete pattern reproduction on SAMs of Boc- and TBS-protected thiols immobilized on gold using a polyurethane-acrylate stamp functionalized ...
    • Simultaneous two-wavelength transmission quantitative phase microscopy with a color camera. 

      Rinehart, Matthew T; Shaked, Natan T; Jenness, Nathan J; Clark, Robert L; Wax, Adam (Opt Lett, 2010-08-01)
      We present a quantitative phase microscopy method that uses a Bayer mosaic color camera to simultaneously acquire off-axis interferograms in transmission mode at two distinct wavelengths. Wrapped phase information is processed ...
