RNA nanotechnology - fewer structures in living cells than in test tubes

Posted by Jim Lewis on January 14th, 2014

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.

New Report: Nano-solutions for the 21st century

Posted by Stephanie C on December 20th, 2013

A recently released technology report titled Nano-solutions for the 21st century outlines nanotech-based solutions to global challenges.

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.

Warped graphene molecules offer new building blocks for nanotechnology

Posted by Jim Lewis on August 26th, 2013

Graphene molecules a bit more than one nanometer across and greatly distorted from planarity have altered properties and offer novel building blocks for nanotechnology.

Illuminating Atomic Precision Conference videos

Posted by Jim Lewis on August 23rd, 2013

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.

Molecular sponges give atomic structures of trace substances

Posted by Jim Lewis on August 8th, 2013

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.
