DNA‐Origami‐Driven Lithography for Patterning on Gold Surfaces with Sub‐10 nm Resolution

Sub‐10 nm lithography of DNA patterns is achieved using the DNA‐origami stamping method. This new strategy utilizes DNA origami to bind a preprogrammed DNA ink pattern composed of thiol‐modified oligonucleotides on gold surfaces. Upon denaturation of the DNA origami, the DNA ink pattern is exposed....

Description
Summary:Sub‐10 nm lithography of DNA patterns is achieved using the DNA‐origami stamping method. This new strategy utilizes DNA origami to bind a preprogrammed DNA ink pattern composed of thiol‐modified oligonucleotides on gold surfaces. Upon denaturation of the DNA origami, the DNA ink pattern is exposed. The pattern can then be developed by hybridization with complementary strands carrying gold nanoparticles.
