I’ll describe recent experiments in our group where we couple rheology measurements to space and time-resolved dynamic light scattering, aiming at understanding the relationship between microscopic dynamics and linear and non-linear viscoelastic properties. I’ll show that the microscopic dynamics is a very sensitive indicator of the ultimate fate of soft solids, able to detect precursors signs of failure well ahead other microscopic or macroscopic quantities [1,2]. I’ll then focus on mucus gels, where an unexpected acceleration of the microscopic dynamics is seen upon applying a very modest shear strain, well within the rheological linear regime .
