“The determination of the double helical structure of DNA in 1953 remains the landmark event in the development of modern biological and biomedical science. This structure has also been the starting point for the determination of some 2000 DNA crystal structures in the subsequent 68 years.”

“The origins of DNA nanotechnology are rooted in the goal of assembling DNA molecules into designed periodic arrays, i.e., crystals. Here, we highlight several DNA crystal structures, the progress made in designing DNA crystals, and look at the current prospects and future directions of DNA crystals in nanotechnology.”

3D DNA Crystals and Nanotechnology

DNA’s molecular recognition properties have made it one of the most widely used biomacromolecular construction materials. The programmed assembly of DNA oligonucleotides has been used to create complex 2D and 3D self-assembled architectures and to guide the assembly of other molecules. The...

“In his role as Amun-Ra, the god combines his invisible aspect (symbolized by the wind which one cannot see but is aware of)…”

"Amun was considered no more powerful or significant than the other gods who were part of the Ogdoad but represented the element of "hiddenness" or "obscurity" while the others represented more clearly defined concepts such as "darkness," "water," and "infinity." Amun as "The Obscure One....."

Amun

Amun (also Amon, Ammon, Amen, Amun-Ra) is the ancient Egyptian god of the sun and air. He is one of the most important gods of ancient Egypt who rose to prominence at Thebes at the beginning of the...
