The authors introduce a direct method for determining droplet solid-liquid-vapor interfacial geometry on microstructured surfaces. A heated liquid metal droplet of size 18 μl is deposited onto a microstructured surface and then freezes, preserving the microstructure impressions onto the metal surface. Postsolidification microscopy can measure contact line geometry and identify wetting state. This approach can be used to visualize contact line on curved and opaque microstructured surfaces.
