ISR Flip: An interfacial shear rheometer based on a mobile magnetic trap

The mechanical properties of interfaces separating two immiscible fluids have a substantial influence on the dynamics of numerous in vivo and industrial systems such as cells, lung alveoli, emulsions, and foams. Since the ability of complex interfaces to withstand stresses can govern the macroscopic behavior of such systems, an instrument allowing for the quantification of the interfacial shear dynamic moduli (viscous and elastic modulus) is an excellent tool to study this kind of materials.
