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 (), and the polymer () and solv…
