1. A structure, comprising:
a patterned, porous membrane having a plurality of pre-designed patterned pores through the patterned, porous membrane, wherein one or more portions of the patterned, porous membrane are disposed on a substrate, wherein a portion of the pores are not blocked by the substrate, wherein the substrate is made of a first material selected from the group consisting of: silicon, metal, quartz, and ceramic, wherein the patterned, porous membrane is made of a second material selected from the group consisting of: SiO2, Si3N4, Al2O2, ZrO2, HfO2, TiO2, aluminum, iron, copper, titanium, polyimide, PMMA, PDMS, and a combination thereof, wherein the pores have a longest dimension across the pore of about 1 nm to 100 μm, wherein the longest dimension can be a diameter, width, length, hypotenuse, or other dimension between two points of the pore opening that are at a greatest distance apart than any other two points along the pore opening, and wherein the patterned, porous membrane has a thickness of about 50 nm to 100 μm. |
