Multi scale hierarchical structures underpin mechanical, optical, and wettability behavior in nature. Here we present a novel approach which can be used to mimic the natural hierarchical patterns in a quick and easy maskless fabrication. By using two‐beam interference lithography with angle‐multiplexed exposures and scanning, we have successfully printed large‐area complex structures having a cascading...
Rice leaves with anisotropic sliding properties have the ability to directionally control the movement of water microdroplets. However, the realization of artificial anisotropic sliding biosurfaces has remained challenging. It is found, by a systematic investigation, that the height of 200‐μm‐width groove arrays on rice leaves reaches up to 45 μm, far greater than the smaller microgrooves that are...
