Using Optical Tweezers for the Characterization of Polyelectrolyte Solutions with Very Low Viscoelasticity
Recently, optical tweezing has been used to
provide a method for microrheology addressed to measure the
rheological properties of small volumes of samples. In this work,
we corroborate this emerging field of microrheology by using
these optical methods for the characterization of polyelectrolyte
solutions with very low viscoelasticity. The influence of
polyelectrolyte (i.e., polyacrylamide, PAM) concentration, specifically
its aging, of the salt concentration is shown. The close
agreement of the technique with classical bulk rheological
measurements is demonstrated, illustrating the advantages of the technique
