Abstract
Many experiments have been performed using microscopic beads to probe the small-scale mechanics of actin solutions. We calculate the minimum bead size needed to measure a valid macroscopic response function. We find that the quasi-static response is characterized by an anomalous scaling as a function of the size of the probing particles.Keywords
