Following the Behavior of the Flagellar Rotary Motor Near Zero Load
(Springer Verlag, 2009)At room temperature at stall, the flagellar motor of the bacterium Escherichia coli exerts a torque of ~1300 pN nm. At zero external load, it spins ~330 Hz. Techniques for studying the motor near zero load are novel and ... -
Imaging Multiple Colloidal Particles by Fitting Electromagnetic Scattering Solutions to Digital Holograms
(Elsevier BV, 2012)Digital holographic microscopy is a fast three-dimensional (3D) imaging tool with many applications in soft matter physics. Recent studies have shown that electromagnetic scattering solutions can be fit to digital holograms ... -
Using the discrete dipole approximation and holographic microscopy to measure rotational dynamics of non-spherical colloidal particles
(Elsevier BV, 2014)We present a new, high-speed technique to track the three-dimensional translation and rotation of non-spherical colloidal particles. We capture digital holograms of micrometer-scale silica rods and sub-micrometer-scale ...
