Lowering Barriers To DNA-based Nanomanufacturing
2012-12-14 11:12:22

Technische Universitaet Muenchen Two major barriers to the advancement of DNA nanotechnology beyond the research lab have been knocked down. This emerging technology employs DNA as a programmable building material for self-assembled, nanometer-scale structures. Many practical applications have been envisioned, and researchers recently demonstrated a synthetic membrane channel made from DNA. Until now, however, design processes were hobbled by a lack of structural feedback. Assembly was...

In a report issued to President Barack Obama on Thursday, his Council of Advisors on Science and Technology said that the United States needs to invest more in nanotechnology if it wants to maintain a global lead in the promising field. The council reported that between 2003 and 2008, US public and private nanotechnology investments grew at about 18 percent annually, compared to 27 percent throughout the world. The council made recommendations that would help bring the US back to the...

Researchers at the University of Pennsylvania, the University of Wisconsin-Madison and IBM Research-Zrich have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more wear-resistant at the nanoscale than silicon. The end result is a diamond-like carbon material mass-produced at the nanoscale that doesn't wear. The new nano-sized tip, researchers say, wears away at the rate of one atom per micrometer of sliding on a substrate of silicon...

The first real steps towards building a microscopic device that can construct nano machines have been taken by US researchers. Writing in the peer-reviewed publication, International Journal of Nanomanufacturing from Inderscience Publishers, researchers describe an early prototype for a nanoassembler.In his 1986 book, The Engines of Creation, K Eric Drexler set down the long-term aim of nanotechnology - to create an assembler, a microscopic device, a robot, that could construct yet smaller...
