Self-organised microdots formed by dewetting in a highly volatile liquid

► Solvent evaporation induced dewetting leads to ordered microdots. ► Stick-slip motion and fingering instability of the contact line. ► Parameters affecting the size and order of the microdots are investigated. ► Size, density and shape of microdots are altered by using micro printed substrates. ► Fe2O3 micropatterns are obtained by thermal treatment.
