Non-Brownian Microrheology of a Fluid Gel Interface
Erik K. Hobbie, Sheng Lin-Gibson, S K. Kumar
We use stroboscopic video microscopy to study the motion of a sheared fluid-gel interface. External mechanical noise plays a role analogous to temperature, but with a low-frequency breakdown of linear response consistent with an underlying instability. We relate the fast motion of the interface to the rheological properties of the gel, laying the foundation for a non-Brownian optical microrheology.
