Protecting the nanotechnology workforce

(Free ebooks) – Nanotechnology—the manipulation of matter on a near-atomic scale to produce new materials and devices—has the ability to transform many industries, from medicine to manufacturing, and the products they produce. By 2020, the National Science Foundation estimates, nanotechnology will have a $3 trillion impact on the global economy and employ 6 million workers in the manufacture of nanomaterial-based products, of which 2 million may be manufactured in the United States [NSF 2011]. Nanomaterials may present new challenges to understanding, predicting, and managing potential health risks to workers.

Video of virus-sized particle trying to enter cell

(Phys.org) – Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nanoparticles—which are about the same size as viruses—as well as how to prevent viral infection from occurring.

Nanotechnology to help healing hearts

(Phys.org) – Precision is also required in the large strategic research opening by Tekes which Franssila and his research group are participating in with the University of Helsinki and Helsinki University Central Hospital. The project has an ambitious goal: getting damaged organs to heal themselves. Achieving this goal requires drugs that are targeted at an organ, such as the heart or the brain, using nanotechnology. The drugs then locally enhance the differentiation of stem cells so that the necessary new heart or nerve cells are created.

Nanotechnology treated contact lenses may improve glaucoma treatment

(Nanowerk) – By 2020, nearly 80 million people are expected to have glaucoma, a disorder of the eye that, if left untreated, can damage the optic nerve and eventually lead to blindness. The disease often causes pressure in the eye due to a buildup of fluid and a breakdown of the tissue that is responsible for regulating fluid drainage. Doctors commonly treat glaucoma using eye drops that can help the eye drain or decrease fluid production.

U.S. government accountability office finds flaws in nation’s approach to nanotechnology manufacturing

(Nanowerk News) – In a new report on nanotechnology manufacturing (or nanomanufacturing) released yesterday (“Nanomanufacturing: Emergence and Implications for U.S. Competitiveness, the Environment, and Human Health”; pdf), the U.S. Government Accountability Office finds flaws in America’s approach to many things nano. At a July 2013 forum, participants from industry, government, and academia discussed the future of nanomanufacturing; investments in nanotechnology R&D and challenges to U.S. competitiveness; ways to enhance U.S. competitiveness; and EHS concerns.

Growing stem cells on carbon nanotubes

(Genetic Engineering & Biotechnology News) – A research team at the University of Surrey and the University of California-Irvine say they developed a scaffold of carbon nanotubes upon which human embryonic stem cells can be grown into a variety of tissues. These new building blocks reportedly mimic the surface of the body’s natural support cells and act as scaffolding for stem cells to grow on. Cells that have previously relied on external living cells can now be grown safely in the laboratory, paving the way for revolutionary steps in replacing tissue after injury or disease, according to the scientists.

Nanotechnology – Moving beyond the hype

(Nanotechnology Now) – Despite significant scientific progress in the field of nanotechnology in the last few decades, currently the most formidable displays of the power of nanoscale processes are performed by nature not artificially and exist inside every single one of us, such as the autonomous replication of the genome and the construction and self-assembly of protein from base amino acids. As a result, it seems reasonable to assume that the route to ultra-advanced computational, engineering and construction projects can in many cases only realistically be achieved through mastery of matter at the atomic scale.
