Figure 3.

Effects of laminar flow on the sample during incubation. (a) Different layers of liquid move at different velocities in the channel, generating a distribution of incubation times. This is represented as different lengths of filament growth (Mäeots et al., 2020 ▸). When a droplet is generated at the end of the channel it contains a mixture of all species, in accordance with their prevalence. (b) Histogram of the residence-time distribution (RTD) due to laminar flow. Dark blue is 15–25 ms and contains 33% of the total data. Light blue is 0–40 ms and contains 70% of the total data. For further details, see Mäeots et al. (2020 ▸).
