Caption: These scanning electron microscope images reveal how UV laser light changes the surface texture and wettability of glass. Figures (a) and (b) reveal subtle texturing after lower-energy exposure to laser light. These textures made the surfaces more hydrophilic in (a) and more hydrophobic (water repellent) in (b). Higher energies produced a rougher and even more hydrophilic (wettable) (c) and (d) close-up of (c), surface.
