Better Use Of Nanotubes As Measuring Tips

Advances with atomic force microscope accuracy advance us on the path towards molecular manufacturing. However, this does not achieve 0.5 angstrom accuracy as some Scanning Electron Microscopes have. It does help more labs get greater accuracy. Engineers at Purdue University have shown how researchers might better use tiny hollow fibers called “multi-walled carbon nanotubes” to …

Nanoparticle enhanced protein detection for medical diagnosis

This is not molecular manufacturing related but improved ability to detect proteins is part of enhanced protein handling that can be part of a protein based assembler. Northbrook, Illinois-based Nanosphere is preparing to launch a diagnostic system that uses nanoparticles to detect various proteins at a level of sensitivity never before seen. Scientists know that …

Engineers build DNA ‘nanotowers’ with enzyme tools

This work is advancing the DNA-Protein-enzyme pathway to molecular manufacturing. It is a process that is advancing toward scalable industrialized processes. Engineers build DNA ‘nanotowers’ with enzyme tools Duke engineers have added a new construction tool to their bio-nanofabrication toolbox. Using an enzyme called TdTase, engineers can vertically extend short DNA chains attached to nanometer-sized …

China’s Military and economy

There is an article and report by the Center for Economic and Policy Research (CEPR) where there are projections of a deficit in US military spending as China’s economy grow. The assumptions in this report and the time frame is nuts. They are talking about a big deficit in 2050-2080 assuming higher than US per …

MIT launches global medical nanotech (not molecular manufacturing) push

Leaders of 10 research universities from around the world will gather at the Massachusetts Institute of Technology today to launch an international collaboration to use nanotechnology tools for global health and medical research. The collaboration, called GEM4, or Global Enterprise for Micro-Mechanics and Molecular Medicine, represents an ambitious effort to apply global sourcing principles to …

Protein-based assembly of nanoscale parts

Robert Bradbury provides a broad analysis of protein-based assembly He discusses recent capabilities in molecular electronics (rotaxane) and organic chemistry. He describes why the march of progress in computers, computer aided enzyme design and algorithms are lowering the cost necessary to advance protein assembly to be able to manufacture a programmable nano-assembler (PNA). Probably in …

Advance in buckyball-polymer solar efficiency

Organic solar cells being developed by the team at New Mexico State University and Wake Forest are made of plastic that is relatively inexpensive, flexible, can be wrapped around structures or even applied like paint, said physicist Seamus Curran, head of the nanotechnology laboratory at NMSU. The level of energy conversion has been a problem …
