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).
Claims11
A method for forming nanopores comprising:
- (A) preparing a dispersion of a plurality of gold nanoparticles;
- (B) dipping a membrane in the dispersion to attach the plurality of gold nanoparticles to a first surface of the membrane;
- and
- (C) heating the membrane attached with the plurality of gold nanoparticles to a predetermined processing temperature such that surface layers of the plurality of gold nanoparticles are liquefied and evaporated, to form nanopores with predetermined shapes on the membrane,
- wherein the nanopores penetrate the membrane from the first surface of the membrane to a second surface of the membrane opposite to the first surface to form open shapes, or are recessed from the first surface of the membrane to form closed shapes, and
- wherein at least a portion of the plurality of gold nanoparticles are removed from the membrane.
