Active microrheology to determine viscoelastic parameters of Stokes-Oldroyd B fluids using optical tweezers

Shuvojit Paul, Avijit Kundu, Ayan Banerjee

We use active microrheology to determine the frequency dependent moduli of a linear viscoelastic fluid in terms of the polymer time constant ($\lambda$), and the polymer (${\mu }_p$) and solv…
