Back-Focal-Plane Imaging and Linear Density Measurements Of Sub-Diffraction Sized Biological Filaments and Particles
Ilya M Beskin, Jordan Zesch, Emma Hunt +2
Optical tweezers equipped with position detection allow for application of piconewton-scale forces and high-temporal-resolution measurements of nanometer-scale motion. While typica…
Direct observation of ballistic Brownian motion on a single particle
Rongxin Huang, Branimir Lukic, Sylvia Jeney +1
At fast timescales, the self-similarity of random Brownian motion is expected to break down and be replaced by ballistic motion. So far, an experimental verification of this predic…
Direct measurement of the nonconservative force field generated by optical tweezers
Pinyu Wu, Rongxin Huang, Christian Tischer +2
The force field of optical tweezers is commonly assumed to be conservative, neglecting the complex action of the scattering force. Using a novel method that extracts local forces f…
Comment on Influence of non-conservative optical forces on the dynamics of optically trapped colloidal spheres: The fountain of probability, arXiv:0804.0730v1
Rongxin Huang, Pinyu Wu, Ernst-Ludwig Florin
We demonstrate that the data presented in the manuscript by Y. Roichman et al. are not sufficient to show that the circulation of a trapped particle exists in a static optical trap…
Development of a Fast Position-Sensitive Laser Beam Detector
Isaac Chavez, Rongxin Huang, Kevin Henderson +2
We report the development of a fast position-sensitive laser beam detector with a bandwidth that exceeds currently available detectors. The detector uses a fiber-optic bundle that…
Microtubule dynamics depart from wormlike chain model
Katja M. Taute, Francesco Pampaloni, Erwin Frey +1
Thermal shape fluctuations of grafted microtubules were studied using high resolution particle tracking of attached fluorescent beads. First mode relaxation times were extracted fr…
