Abstract
A method of selectively modifying a structure including preparing a structure including a nano-sized through-pore, filling the nano-sized through-pore with a surfactant, removing a portion of the surfactant from both ends of the nano-sized through-pore to expose a portion of an internal surface of the nano-sized through-pore, modifying the exposed internal surface of the nano-sized through-pore with a first compound, removing the surfactant from the nano-sized through-pore having the internal surface modified with the first compound to expose an internal surface that remains unmodified with the first compound, and modifying with a second compound the exposed internal surface without being modified with the first compound, the second compound being different from the first compound.
