A very large community of online gamers has consistently produced RNA designs that outperform the best design algorithms by a large margin. Can online gamers designing RNA, protein, and other molecules contribute to the development of atomically precise manufacturing?
A reconstituted high-density lipoprotein nanoparticle reduces inflammation in advanced atherosclerotic plaques in mice. Will it work in humans to prevent repeat heart attacks and stroke?
A DNA clamp engineered for higher specificity and higher affinity may improve cancer diagnosis and treatment and may also mean better control over building nanomachines.
A possible forerunner to a future molecular assembly line uses an artificial DNA motor to transport an artificial nanoparticle along a carbon nanotube track.
A study of RNA structures actually present in cells reveals that cells spend energy restricting thermodynamically driven RNA folding so that fewer RNA structures are found in cells than in test tubes.
A collection of open access journals on a variety of topics provides a very useful entry point to the rapidly growing collection of scientific, technical, and scholarly research that is not hidden behind pay walls.
Using DNA nanotechnology to control and organize molecular motors and the molecular tracks that they run on, a novel nanotrain transports molecular cargos tens of micrometers.
A new book by Frank Boehm explores the challenges, possibilities, and visions of nanomedical device and systems design.
A nanoribbon transistor no thicker than the distance between adjacent DNA bases provides high resolution sensing of DNA passage through nanopores, perhaps leading eventually to rapid DNA sequencing.
Gold nanoparticles densely coated with RNA molecules intended to silence a gene essential for an incurable brain cancer proved effective in mice engrafted with human glioblastoma multiforme tumor.
Modifying DNA strands with lipid-like molecules opens more possibilities for designing DNA structures for drug delivery and other purposes.
A major advance in the computational design of proteins that bind tightly to specific small molecules will facilitate several technologies, possibly including the development of atomically precise manufacturing.
Nanotechnology draws from physics, chemistry, engineering, computation, etc., and this multi-disciplinary nature has served as a major speed bump in achievement of envisioned nanotech goals. There has been substantial concern that the U.S. is lagging behind other countries in nanotech R&D. Now researchers, companies, and politicians are coming together to create a much-needed physical hub [...]
How complex could circuits be made using precisely positioned DNA nanostructures as templates to grow graphene nanoribbons?
“Molecular threading”, a nanotechnology developed by Halcyon Molecular and now owned by Aeon Biowares, enables precise placement of individual long molecules of DNA, either for sequencing or for nanofabrication of novel DNA nanostructures.
The Conference to be held February 7-9, 2014 in Palo Alto, California will emphasize the integration of nano-engineered devices and materials into larger, more complex systems.
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 [...]
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. [...]
A pillar constructed and positioned using DNA nanotechnology holds two gold nanoparticles and a dye molecule to enhance fluorescence over a hundred fold.
