We study the heterogeneity of gels near the sol-gel transition through the spatial variations in gel strength. The correlated motion of fluorescent polystyrene microspheres suspended in gels (see image at right) is measured via two-point microrheology. Analysis of this correlated motion provides a local measure of gel heterogeneity. |
