Tomáš Vičar and his team present an approach for viscoelasticity measurement using QPI and shear stress induction by fluid flow. It allows to eliminate the influence of the fluidic system and reliably measure both the shear modulus and viscosity of the cells in high throughput.

The described method enables also the simultaneous determination of cell refractive index map, cell dry mass map, and morphology (multimodal cellular characterization in a single measurement).

The measurements were done on Telight Q-Phase.
