Robust triangular RNA brick adds to RNA nanotechnology toolkit

Posted by Jim Lewis on June 24th, 2014

The complex molecular recognition code of RNA offers RNA nanotechnology a greater variety of 3D structures and functions than are present in DNA nanotechnology, but the RNA structures can be fragile. New RNA triangles that resist boiling solve this problem.

To fight inflammation nanoparticles turn 'naughty' neutrophils into 'nice' neutrophils

Posted by Jim Lewis on May 1st, 2014

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

Posted by Jim Lewis on April 29th, 2014

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.

US government report highlights flaws in US nanotechnology effort

Posted by Jim Lewis on April 1st, 2014

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.

Chemists provide new tool for nanotechnology-modifying the right carbon atom

Posted by Jim Lewis on March 27th, 2014

A new tool to chemically modify one specific carbon atom among several chemically very similar ones will facilitate building larger, more complex molecules for drug discovery and for nanotechnology.
