Experimental and theoretical data in Figure 8 are in good agreement, and hence eq 14 affords a rather precise determination of the particle concentration for a known particle diameter, where the average absolute deviation of N determined from eq 14 as
compared to the experiment was 6%. Numerical data of (d)at ì ) 450 nm, which allow the reader to determine the concentration of GNPs without the need to perform calculations, are presented in the Supporting Information
