In fall 1980, while at a campus pub, Seeman was inspired by the
M. C. Escher
Maurits Cornelis Escher (; 17 June 1898 β 27 March 1972) was a Dutch graphic artist who made mathematically inspired woodcuts, lithographs, and mezzotints.
Despite wide popular interest, Escher was for most of his life neglected in t ...
woodcut ''Depth'' to realize that a three-dimensional lattice could be constructed from DNA. He realized that this could be used to orient target molecules, simplifying their crystallographic study by eliminating the difficult process of obtaining pure crystals.
In pursuit of this goal, Seeman's laboratory published the synthesis of the first three-dimensional nanoscale object, a cube made of DNA, in 1991. This work won the 1995
Feynman Prize in Nanotechnology
The Feynman Prize in Nanotechnology is an award given by the Foresight Institute for significant advances in nanotechnology. Two prizes are awarded annually, in the categories of experimental and theoretical work. There is also a separate chall ...
. The concept of the dissimilar double
DNA crossover introduced by Seeman, was important stepping stone towards the development of
DNA origami
DNA origami is the nanoscale folding of DNA to create arbitrary two- and three-dimensional shapes at the nanoscale. The specificity of the interactions between complementary base pairs make DNA a useful construction material, through design of ...
. The goal of demonstrating designed three-dimensional DNA crystals was achieved by Seeman in 2009, nearly thirty years after his original elucidation of the idea.
The concepts of DNA nanotechnology later found further applications in
DNA computing
DNA computing is an emerging branch of unconventional computing which uses DNA, biochemistry, and molecular biology hardware, instead of the traditional electronic computing. Research and development in this area concerns theory, experiments, a ...
