Figure 5.
a) Fluorescence image of the inlet reservoir and b) of the center outlet reservoir solution after sorting a highly polydispersed, larger volume sample (+60V inlet, −60V center outlet, −5V MO and O side outlets). Scale bars are 50 μm. In c) and d) a histogram of the size distribution from an imaging threshold analysis is shown in which a wide range of particle sizes from 800 nm to 20 μm are detected for both the bulk and center outlet solutions. The lower limit of detection for this method is 800 nm, therefore, nanocrystals below 800 nm could not be individually resolved.
