摘要: In one aspect, methods of nanopore formation in solid state membranes are described herein, In some embodiments, a method of forming an aperture comprises providing at least one solid state membrane in a chamber, selecting a first dose of ions sufficient to provide a first aperture of predetermined diameter through the membrane and exposing a surface of the membrane at a first location to the first dose of ions in a focused ion beam having a focal point of diameter less than or equal to about 1 nm to remove material from the membrane at the first location thereby providing the first aperture having the predetermined diameter or substantially the predetermined diameter.
