Graphene molecules a bit more than one nanometer across and greatly distorted from planarity have altered properties and offer novel building blocks for nanotechnology.
A limited set of videos from the January 2013 Foresight Conference have been made available. John Randall started the Conference presentations describing the patterned silicon Atomic Layer Epitaxy (ALE) approach to atomically precise manufacturing.
Covalent bonding of nanocrystals into a glass makes the glass ‘smart’ enough to transmit heat, light, both, or neither as desired.
In simplest terms, cellular automata can be thought of as groups of ‘cells’ in which the state of an individual cell will flip depending on the states of its neighbors. A ‘cell’ can be a pixel, a molecule, etc. The mathematical rules associated with cellular automation are complex and have been applied to fields as… Continue reading Improved molecular targeting via cellular automata
A porous metal-organic framework ‘host’ soaks up molecular ‘guests’ to form a crystalline complex, the structure of which can be determined by X-ray crystallography, providing atomic-resolution structures of minute amounts of guest molecules, and perhaps eventually other nanostructures.
Good old fashioned boxes are here to stay, even in the context of nanoscale devices. Across a broad range of technologies and size regimes, boxes serve as containers for components, barriers against contaminants and/or radiation, and, as in the case of cell membranes, can be permeable to allow selected interactions between the interior and exterior.… Continue reading Nanoscale box aids single-molecule optical detection
A pillar constructed and positioned using DNA nanotechnology holds two gold nanoparticles and a dye molecule to enhance fluorescence over a hundred fold.
Two current-day nanotechnologies using two-different optical techniques and two different media will soon make possible petabyte data storage media, in one case with 100,000 times the storage lifetime of current optical disks.
Two open access reviews portray the widening approach of DNA nanotechnology toward more complex atomically precise systems.
A simple DNA scaffold organizes light-collecting molecules for artificial photosynthesis.
