Get PDFSummary Semiflexible polymers are of great biological importance in determining the mechanical properties of cells. We have used laser interferometry to passively trap and detect the motions of pairs of micron sized silica spheres in solutions of semiflexible polymer. The single-and dual-bead frequency dependent complex shear moduli were extracted from the auto-and cross-correlation response of the beads respectively, with the response being derived from position fluctuation data using dispersion relations from linear response theory
Describing Surfaces**This report describes research done at the Artificial Intelligence Laboratory of the Massachusetts Institute of Technology. Support for the laboratory's Artificial Intelligence research is provided in part by the System Development Foundation, the Advanced Research Projects Agency of the Department of Defense under Office of Naval Research Contract N00014-80-C-0505, the Office of Naval Research under Contract N00014-77-C-0389, and the System Development Foundation. This work was done while Haruo Asada was a visiting scientist at MIT on leave from Toshiba Corporation, Japan, and while Jean Ponce was a visiting scientist on leave from INRIA, Paris, France.
