1. A method for making a non-superhydrophyllic material superhydrophilic (superwetting), comprising the steps of:

  • a) providing a non-superhydrophilic material having at least one of a smooth, a roughened, and a pre-structured surface; and

    b) processing the surface region of the material using an energy flux comprising at least one of one or more pulses from a suitable energy source and continuous radiation from a continuous energy source, further comprising;

    i) creating one or more indentations in the surface, wherein said one or more indentations have a micro-rough surface comprising at least one of protrusions, cavities, spheres, rods, and other irregularly shaped features having heights and/or widths on the order of 0.5 to 100 microns, 

    further wherein the micro-rough surface has a nano-rough surface comprising at least one of protrusions, cavities, spheres, rods, grooves, and other irregularly shaped features having heights and/or widths on the order of 1 to 500 nanometers.
