, respectively. The above numbers obtained from the fractal analysis do indicate that the
above analyzed runs are reversible. The error exhibited in the fractal dimension is relatively
small. Note that the fractal dimension is based on a log scale, and even small changes in the
fractal dimension indicate significant changes in the degree of heterogeneity that exists on the
biosensor surface.
