From: Immunological assay using a solid-state pore with a low limit of detection
Quantitative analysis of mixed solutions of polystyrene beads with diameters of 300, 500, and 600 nm at different mixing ratios. Pulse height (Ip) histograms obtained by solid-state pore measurement of solutions mixed in the ratio 300 nm:500 nm:600 nm at (a) 1:3:2, (b) 2:3:1, (c) 3:1:2, (d) 3:2:1. (e) Comparison between the mixing ratio estimated by solid-state pore measurement and the actual mixing ratio: 300 nm:500 nm:600 nm. The color codes of the Ip histograms match the color codes of the ratio bars.
