We modify optical and wetting properties of solids using a femtosecond laser surface nanostructuring technique. We demonstrate that this technique allows creating black and color metals. Absorptance of black titanium created in our study is measured to be about 90-97% over a broad wavelength range from the ultraviolet to infrared. Moreover, our technique can be also used for modifying wetting properties of solids. Here, we create a novel surface structure that transforms regular silicon to superwicking. This surface structure makes water run vertically uphill in a gravity defying way. Our study of the liquid motion shows that the extraordinarily strong self-propelling motion of water is due to a capillary effect from the surface structures we created.
