Microrheology of cross-linked polyacrylamide networks

Experiments investigating the local viscoelastic properties of a chemically cross-linked polymer are performed on polyacrylamide solutions in the sol and the gel regimes using polystyrene beads of varying sizes and surface chemistry as probes. The thermal motions of the probes are measured to obtain the elastic and viscous moduli of the sample.

passive and active microrheology for cross-linked f-actin

Passive and active microrheology for cross-linked F-actin

Further study of strain-dependent microrheology for F-actin networks cross-linked with other ABPs will provide a better understanding of the microscopic origin of non-linear behavior in the F-actin networks. The effects of ABP concentration are similar at the microscale to previous macroscale measurements.

Passive and active microrheology for cross-linked F-actin

Effects of probe size, filament length and measurement method on microrheology of cross-linked F-actin networks. Using a larger microsphere with radius a = 1 渭m, the complex shear moduli are estimated for the F-actin networks polymerized in the absence (A) and presence (B) of gelsolin.
