Novel multifunctional nanoparticle for diagnosis and therapy

Posted by Jim Lewis on September 14th, 2014

A nanoparticle that self-assembles from porphyrin, cholic acid, amino acids, and polyethylene glycol is a promising vehicle for delivering both imaging agents and cancer drugs to tumors.

What kind of nanomachines will advanced nanotechnology use?

Posted by Jim Lewis on August 31st, 2014

An interview with UK nanotechnologist Richard Jones argues that the surest and most efficient path to advanced nanomachine function will incorporate or mimic biomolecular nanomachinery rather than scaled down rigid conventional machinery.

The photos from the 2014 Foresight Technical Conference highlight entrepreneurial efforts in space, biotechnology, and life extension.

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.

Notes on 2014 Foresight nanotechnology conference

Posted by Jim Lewis on March 7th, 2014

A “sense of energy, momentum, and collegiality throughout the weekend” united attendees hearing about the integration of nano-engineered devices and materials into more complex systems, and the integration of nanoscale technologies into diverse applications.

In mice, nanoparticle reduces inflammation in atherosclerotic plaques

Posted by Jim Lewis on March 5th, 2014

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?

Better nanoswitches by integrating double and triple strand DNA

Posted by Jim Lewis on January 28th, 2014

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.

Graphene nanoribbon senses passage of individual bases of DNA

Posted by Jim Lewis on November 19th, 2013

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.

Nanoparticle therapy for incurable brain cancer effective in mice

Posted by Jim Lewis on November 15th, 2013

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.
