cells is hence where u03c1 tot u2261 n tot v 0 then eq 1 is derived by using the conductance formulation for an evaporating droplet eq s3 in si and defining the per cell conductivities as u03c3 l d t lt u03bc gt r l d t lt u03bc gt and r l d t are the effective mobility and the number of released ions from individual live dead cells respectively here h z represents the time invariant length of the deposited droplet based on eq 1 the initial conductance g i u03b1 at t i and final conductance g f u03b1 at t f would be time dependent conductance values for samples with all alive u03b1 1 and all dead u03b1 0 cells are plotted in fig3 a and 3 b by inserting g i 1 g f 1 g i 0 and g f 0 indicated by arrows into eq 2 and 3 we extracted u03c3 l i u03c3 l f u03c3 d i and u03c3 d f which are plotted in fig3 c the lines in fig3 c represent the fitted curves with a power law dependence of u03c3 on u03c1 tot u03c3 u2248 a u03b1 u03c1 tot b u03b1 the extracted values of u03c3 are used in estimation of u03c1 tot and u03b1 in seven different samples for a given sample with measured initial.
