Self-assembled monolayers of a malachite green derivative: Surface with pH- and UV-responsive wetting properties

Surfaces that respond to pH and UV stimuli are fabricated from self-assembled monolayers (SAMs) of a malachite green derivative on a rough surface (see figure). The wetting properties of the SAMs exhibit an uncommon response to pH and UV illumination, and range from superhydrophobicity to superhydrophilicity.
