WebWe make a parallel excursion to the generalised Maxwell and Kelvin-Voigt models to find which general conditions may lead to the weak power law behaviours of the elastic and viscous moduli, G′(w)∼G′′(w)∼wα, with 0<1. These occur in a wide variety of soft materials, including living cells. We find that these behaviours are obtained for … WebMicrorheology[1]is a technique used to measure the rheological propertiesof a medium, such as microviscosity, via the measurement of the trajectory of a flow tracer(a micrometre-sized particle). It is a new way of doing rheology, traditionally done using a rheometer.
