Abstract

The biaxial confinement of a semiflexible filament in a channel was investigated using high resolution video microscopy. A single chain of F-actin was found to undergo fluctuations with characteristic time scales of seconds at room temperature. A mode was introduced to study the tangent-tangent correlation function of confined F-actin. The results showed that with decreasing channel width, F-actin undergoes a transition from 2D randomly oriented regime to a 1D biaxially confined regime.
