Semiflexible polymers are of great biological importance in determining the mechanical properties of cells. We have used optical tweezers to trap pairs of micron-sized silica spheres in solutions of semiflexible polymers, and laser interferometry to detect their thermal motions with high bandwidth. Frequency-dependent complex shear moduli were extracted from the auto- and cross-correlated bead motions,...
We present techniques based on optical trapping of micron-sized particles as probes and detecting their motion with sub-nanometer accuracy at 100 kHz bandwidth that can measure viscoelastic properties of biomaterials and cells on micrometer scales.
