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.

Programmable nanoprocessors integrated into a nanowire nanocomputer

Pioneering a design and fabrication strategy to address individual nanoscale electronic devices to enable large-scale assembly into integrated computer circuits, a MITRE-Harvard team has assembled a functional nanoelectronic control computer.

Notes on 2014 Foresight nanotechnology conference

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

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?

Advanced technologies by design

Design and prediction are integral to Atomically Precise Manufacturing and its development. This is in part because fully functional APM can be readily explored computationally today, to levels of precision that cannot be experimentally developed today. In such a context, design is not just a resource but an approach. With rapidly expanding computational power, examples… Continue reading Advanced technologies by design

Nanotrain uses molecular motors and DNA nanotechnology controls

Using DNA nanotechnology to control and organize molecular motors and the molecular tracks that they run on, a novel nanotrain transports molecular cargos tens of micrometers.

Upcoming Book Explores Nanomedical Device and Systems Design

A new book by Frank Boehm explores the challenges, possibilities, and visions of nanomedical device and systems design.
