Improved molecular targeting via cellular automata

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

Molecular sponges give atomic structures of trace substances

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.

Nanoscale box aids single-molecule optical detection

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

DNA nanotechnology positions components to optimize single-molecule fluorescence

A pillar constructed and positioned using DNA nanotechnology holds two gold nanoparticles and a dye molecule to enhance fluorescence over a hundred fold.

Nanotechnology, optical lithography, and petabyte data storage media

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.

Recent highlights and discussions of APM concepts

The release of Eric Drexler’s new book Radical Abundance has sparked a resurgence of discussion about nanotechnology and the global future. Last month, Nanowerk reprinted Drexler’s blog write-up entitled The Physical Basis of High-Throughput Atomically Precise Manufacturing, a reader-friendly overview highlighting parallels between molecular manufacturing and conventional chemistry and manufacturing. Over the last couple months,… Continue reading Recent highlights and discussions of APM concepts

Reviews of DNA nanotechnology-atomically precise microscale objects

Two open access reviews portray the widening approach of DNA nanotechnology toward more complex atomically precise systems.

Foresight Advisor Doug Engelbart, 1925-2013, will be greatly missed

The visionary technologist who invented the computer mouse and hypertext linking, and helped bring about the Information Revolution joined Foresight in advocating online discussion and argumentation systems for exploring emerging technologies.

DNA nanotechnology builds solar energy antenna

A simple DNA scaffold organizes light-collecting molecules for artificial photosynthesis.

Mass production of higher quality oligonucleotides to spur DNA nanotechnology

Biotechnology-based isolation and amplification of sequence-verified clones of DNA oligonucleotides will provide longer and less expensive materials for building complex DNA nanostructures and nanomachinery.
