Abstract
Disclosed is a method for forming nanopores. The method includes (A) preparing a dispersion of gold nanoparticles (S100), (B) dipping a membrane in the dispersion to attach the gold nanoparticles to the surface of the membrane (S200), and (C) heating the membrane attached with the gold nanoparticles to a predetermined processing temperature such that the surface layers of the gold nanoparticles are liquefied and evaporated, to form nanopores with predetermined shapes on the membrane (S300).
