Two-Particle Microrheology of Quasi-2D Viscous Systems
Two-Particle Microrheology of Quasi-2D Viscous Systems
We study the correlated motions of colloidal particles in a quasi-2D system (Human Serum Albumin (HSA) protein molecules at an air-water interface) for different surface viscosities $η_{s}$. We observe a transition in the behavior of the correlated motion, from 2-D interface dominated at high $η_{s}$ to bulk fluid-dependent at low …
