ECμPs function as negative contrast particles and can be separated from positive contrast particles using an acoustic sample preparation chip. These images were captured via an epifluorescence microscope with a 2.5x objective. Each sample was flowing at 45 μL/min. Fluorescence microscopy images along with histograms of average intensity profiles for Nile Red (NR) stained ECμPs with the field (a) off and then (b) on. (c) NR-ECμPs separated from NR-PS particles with the field on. (d) NR-ECμPs separated from NR-blood cells with the field on. Note: white dashed lines in (a) indicate micro-channel borders.
