Under isothermal conditions (similar to 22 degreesC here), a liquid crystalline (LC) drop at rest onto a structured surface may retract upon an early stage of spreading, leading to the formation of a uniform array of micrometer-scale droplets, which exhibits a high environmental stability in water. We took advantage of this specific dewetting pattern and softness of the LC material to investigate the shear-induced detachment of these adhering micrometer-scale soft objects, induced by the retraction of an evaporating water drop. Two resisting factors were shown to critically control the detachment of the LC droplets: (i) the intrinsic adhesion to the surface via molecular bonds and (ii) the cohesion of a transition layer arising from the homeotropic ordering of the LC molecules near the surface. Both resisting barriers were reduced by setting a slight thermal disorder to the system (T similar to 40 degreesC), leading to the complete detachment of the LC material within the drying drop. These competitive processes of particle sticking vs detachment are relevant to many biological systems. For instance, they may control the drying of biodispersions on tissues or cell-covered substrates. These results may therefore provide some insights into the understanding of these phenomena.
