DNA Nanostructures-Mediated Molecular Imprinting Lithography
This paper describes
the fabrication of polymer stamps using DNA
nanostructure templates. This process creates stamps having diverse
nanoscale features with dimensions ranging from several tens of nanometers
to micrometers. DNA nanostructures including DNA nanotubes, stretched
λ-DNA, two-dimensional (2D) DNA brick crystals with three-dimensional
(3D) features, hexagonal DNA 2D arrays, and triangular DNA origami
were used as master templates to transfer patterns to poly(methyl
methacrylate) and poly(l-lactic acid) with high fidelity.
The resulting polymer stamps were used as molds to transfer the pattern
to acryloxy perfluoropolyether polymer. This work establishes an approach
to using self-assembled DNA templates for applications in soft lithography
