Fig. 3: Droplet velocity and growth over time.
From: Active droploids
a Average size of active droploids (green) and immotile droplets (blue) over time calculated from experiments (dotted) and simulations (solid) for ϕ0 = 0.05. The shaded area represents the standard deviation. The inset shows the delay in the formation of an immotile droplet at early times for an off-critical composition of ϕ0 = 0.25. b Mean (and shaded standard deviation) of the total traveled distance of an active droploid over time measured from experiments (dotted) and simulations (solid). c Simulated active droploid velocity over time. d Velocity distribution of active droploids in experiments (left) and simulations (right). e Simulated mean velocity of active droploids after 30 s of light illumination (black curve) and fraction of non-absorbing particles located at the interface of the droplets \({N}_{{{{{{{{\rm{na}}}}}}}}}^{{{{{{{{\rm{int}}}}}}}}}/{N}_{{{{{{{{\rm{na}}}}}}}}}\) (gray curve simulations, gray dots experimental data fitted with λ = CIρa and C = 3 × 10−4 μm4 μW−1) as a function of the energy input λ for ϕ0 = 0.05. Note that the fitting factor C is different here than in Fig. 2 because the present measurements are based on a fixed concentration of ϕ0 = 0.05, whereas those in Fig. 2 have been taken at various concentrations up to ϕ0 = 0.2. The full list of simulation parameters is provided in the ‘Methods’ section.
