Influence of substrate elasticity on particle deposition patterns from evaporating water-silica suspension droplets

We investigated the evaporation of sessile droplets of water-silica suspensions on deformable polydimethylsiloxane substrates with Young's moduli ranging from 0.2 to 1.5 MPa. We show that substrate elasticity can be employed to control the evaporation patterns and reduce the so-called coffee-st...
