Image of a 5-µL moving reactive droplet in complete wetting. It is composed of a 0.05 M solution of 1H,1H,2H,2H,perfluorodecyltrichlorosilane in octane. The substrate is a glass slide cleaned by corona treatment. The droplet is moving from left to right with a velocity of 10.5 cm⋅s−1, leaving a wake of dry substrate behind (see also Movie S7).
