What is optical microrheology?

Rheology is concerned with understanding how materials flow. A traditional mechanical rotational rheometer measures the rheological properties by applying a stress to the sample and detecting the response to that applied perturbation in various geometries (for example ‘cup and bob’,…READ MORE >
