This article deals with a new domain of rheology, called microrheology, for the measurement of the viscosity and elasticity of materials such as suspensions, gels, and emulsions used in different industries like cosmetic, pharmaceutical, food, and paints.
Topics include:colloid science in food nutrition & the relationship of texture to sensory perception of food materials, it also discusses the exploitation of surfactant mesophases for nanoscale encapsulation, the interfacial rheological properties of mixed interfaces, the dynamics & microrheology of gels & emulsions, the stability of droplets & bubbles, the effects of thermal & mechanical processing on food colloid stability & the electrostatic interactions of proteins with polysaccharides

Using the model, it was observed that the viscosities of PS and PMMA were reduced with the decrease of die diameter, and the slip velocities were increased with the increase of shear stress, which agrees well with polymer microrheology based on the microscale effect.
