Figure 6.

Data of the previous figure for the 3.3E–12 M solution of spores and the control sample, but presenting the apparent refractive index on the x axis and the mean TE-TM spacing on the y axis to put emphasis on the correlation. The gray ellipse corresponds to the threshold set at three standard deviations, beyond which a data point is considered as a biodetection event. The graph in the inset shows the biodetection event percentage for distributions of 50 measurements at different concentrations of B. globigii. spores
