A red blood cell trapped inside a thin fluid filament

The sample snapshot shows a red blood cell being trapped inside a fluid filament undergoing thinning during the final stages of the drop breakup process in a microfluidic device. The experiment is performed in a two-phase flow using a cross-slot microchannel that is 200 micrometers wide and 100 micrometers deep. This research can lead to a better understanding of complex fluid flow phenomena by elucidating how soft deformable particles, such as cells, affect the dynamics and morphology of thinning filaments during drop breakup.
