Novel properties for nanotechnology rebar-graphene reinforced with carbon nanotubes

Carbon-containing functional groups decorating carbon nanotubes decompose upon heating on copper foil to form a nanotube-reinforced graphene with novel properties that mimic those of expensive indium-tin-oxide.

DNA nanotechnology replicates enzyme cascade

A swinging DNA arm added to a DNA scaffold makes it possible for two enzymes attached to the scaffold to complete a coupled chemical reaction.

Expanded DNA alphabet provides more options for nanotechnology

A bacterium has been engineered to stably propagate a DNA written with six letters instead of the usual four, greatly expanding the number of amino acids, both natural and synthetic, that can be genetically encoded. Further work could lead to novel proteins incorporating these additional amino acids, and from there to novel materials, devices, and machines.

Nanotechnology to provide efficient, inexpensive water desalination

Two different nanotechnology-based approaches to use graphene as the basis for purification and desalination of water look promising.

Nanotechnology to provide better solar cells, optical devices

A novel method to control the configuration of atoms in semiconductors grown on graphene will make possible a vast array of new optical devices, including better solar cells.

A bird’s-eye view of half a century of nanotechnology

Reviewing Eric Drexler’s Radical Abundance, Phil Bowermaster provides an informed and insightful overview of the controversies that greeted the proposal for a nanotechnology aimed at developing a practical technology for atomically precise manufacturing. Along the way he shows how Drexler’s outlook evolved from 1986 to 2013.

To fight inflammation nanoparticles turn ‘naughty’ neutrophils into ‘nice’ neutrophils

By targeting the protein that attaches a type of immune cell called neutrophils to blood vessel walls where they cause serious tissues damage, the neutrophils are released and returned to the circulation to resume their normal functions.

Novel nanoparticle efficiently silences gene expression in liver cells

RNA interference provides potential cures for various diseases by silencing the expression of specific genes in specific organs, but delivering the RNA molecules to the right place is very difficult. A novel nanoparticle provides unprecedented efficiency in silencing target genes in liver cells.

Physicists suppress ‘stiction’ force that bedevils microscale machinery

A possible top-down path to atomically precise manufacturing that passes through microscale machinery might be rendered easier because of recent progress in suppressing the Casimir force, which contributes to the ‘stiction’ problem often encountered with microelectromechanical systems.

US government report highlights flaws in US nanotechnology effort

The concern of the US GAO for a gap in nanomanufacturing is well-placed, but it is only half of the problem with the limited US vision of the impact of nanotechnology on the future world economy.
