I need to compute the viscous moduli G" and elastic modulti G' from mean-square deplacement. What are the transformed equations and software to do that?
You have explained in details and it's helpful for me.
By the way, the problem is that I don't understand the reason why: the single-particle microrheology method doesn't agreement with the bulk rheology (see e.g. Dawson, 2001; Celli et al. 2005), whereas the two-particle method does (see Crock 2000)?
I am now working on mucus, in particular its macro/micro-rheology, mesh size.
