Biological systems often use self-assembly (np., proteins folding into precise shapes). In metale, badacze use templates - such as arranged polymer microspheres - that are later removed, leaving behind controlled-size pores. Alternatively, block-copolymer lithography can create extremely regular nascale facarts, which are then transferred into a metal film via elecodeposition or physicar payar deposition.
