The high concentration of particles pins the meniscus, allowing more particles to come to the contact line, until the meniscus becomes so stretched that it depins, swiftly returning to a resting position. This effect is observed in a drying sessile droplet, but also when coupled to particle deposition techniques, such as blade-coating and dip-coating. Dip-coating is a simple process, where a substrate is submerged in a particle suspension and then withdrawn at a constant rate.
