Abstract
The density fluctuation of counterions within an aqueous droplet was investigated using fluctuation-dissipation theorem. The incorporation of charged proteins in the microdroplets alters the percolation threshold of ion fluctuations. The results show that the ion fluctuation grows and becomes saturated with the increase in counterion concentration and the mean-square dipole moment is proportional to the polarizability of the microdroplets.
