Changes in the percolation threshold by cytochrome c addition in AOT reverse micelles

We report changes in the percolation threshold of AOT water droplets by solubilizing cytochrome c, a water-soluble protein. The change of the critical percolation factors (volume fraction, temperature, water content) is attributed to the increase in the attractive interactions between droplets by solubilizing cytochrome c in water droplets. The critical exponents determined from percolation theories are compared using filled and unfilled micelles.
