Fig. 2: Compiled IR histograms with the corresponding mean and standard deviation of detected particles via PANORAMA and bright-field.

Compiled IR histograms of detected PS beads by PANORAMA: a 750 nm (n = 10), b 460 nm (n = 5), c 300 nm (n = 5), d 200 nm (n = 5), e 100 nm (n = 10), f 50 nm (n = 5), and g 25 nm (n = 10). Compiled IR histograms of detected particles by bright-field: h 750 nm (n = 10), i 460 nm (n = 5), j 300 nm (n = 5), and k 200 nm (n = 5). l Corresponding IR histogram of the background from the squared regions in Fig. 1. Each particle size detection was repeated n times. All particles detected from all experiments (n) are used to plot the IR histogram and calculate the mean and standard deviation.
