Nadrian C. "Ned" Seeman Death

Nadrian C. “Ned” Seeman Death – Nadrian C. “Ned” Seeman, an American nanotechnologist and crystallographer known for inventing the field of DNA nanotechnology has passed away on Tuesday, November 16, 2021, at the age of 75. Seeman’s death was made known through social media on November 17, 2021, by “The Bragg Centre and Royce at Leeds” via Twitter. Seeman was described in the post as “the father of DNA nanotechnology”. Also, he was remembered for his immense contribution to the nanotech world. The Bragg Centre and Royce at Leeds wrote on Twitter, “RIP Nadrian Seeman, the father of DNA nanotechnology. You will be forever remembered for your immense contribution to material science and nanotechnology. Thank you for showing us that art can inspire science and that there is more to DNA than just biology.”

Seeman attended the University of Chicago and studied biochemistry, also studied crystallography at the University of Pittsburgh. He became a faculty member at the State University of New York at Albany, and in 1988 moved to the Department of Chemistry at New York University. Seeman rose to fame in the early 1980s for his development of the concept of DNA nanotechnology he commence during that time. In fall 1980, while at a campus pub, Seeman was inspired by the M. C. Escher woodcut Depth to realize that a three-dimensional lattice could be constructed from DNA.

According to Wikipedia, Seeman realized that the three-dimensional lattice 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. Fortunately, In 1995, the research won the Feynman Prize in Nanotechnology. The concept of the dissimilar double DNA crossover introduced by Seeman,[8] was an important stepping stone towards the development of DNA origami. The cause of Seeman’s death has not been made known to the general public.
