Evaporation profile of representative droplets examining the change in radius and phase morphology over five seconds with a time resolution of 60 ms. Due to chaotic scattering of light from crystal/amorphous particles, radius estimations at later time (red points) are unreliable. Evaporation of droplets containing (a) DMEM, 10% FBS and 0% mucin, and (b) DMEM, 10% FBS with 0.5% w/v mucin.
