Nanotechnology study will address concerns about nanoparticle safety
The Royal Society and Royal Academy of Engineering study on nanotechnology will address concerns about the safety of nanoparticles, Professor Ann Dowling, the chair of the working group, said today (30 September 2003), as an update report outlining how the study will progress was published. The study will also consider other potential benefits and... view more... (2003-09-29)

Nanoparticle Assembly Enters the Fast Lane
The speed of nanoparticle assembly can be accelerated with the assistance of the molecule that carries life's genetic instructions, DNA, a team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory recently found.   view more (2006-10-12)

New contrast agents may be on horizon for better medical imaging
Research by scientists based at the University of Illinois at Urbana-Champaign may lead to the development of a new breed of "multimodal" contrast agents that could work within a host of medical imaging platforms — from ultrasound and computed tomography (CT) to magnetic resonance imaging and molecular imaging.   view more (2006-06-08)

Magnetic nano-'shepherds' organize cells
The power of magnetism could be an enabling technology to address a major problem facing bioengineers as they try to create new tissue-getting human cells to not only form structures, but to stimulate the growth of blood vessels to nourish their growth.   view more (2009-04-01)

New silver nanoparticle skin gel for healing burns
Scientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. With names like silver sulfadiazine and silver nitrate, these germ-fighters save lives and speed healing.   view more (2009-07-23)

Implant bacteria, beware: Researchers create nano-sized assassins
Staphylococcus epidermidis is quite an opportunist. Commonly found on human skin, the bacteria pose little danger. But S. epidermidis is a leading cause of infections in hospitals.   view more (2009-06-26)

Metals Shape Up with a Little Help from Friends
For 5,000 years the only way to shape metal has been by the "heat and beat" technique. Even with modern nanotechnology, metalworking involves carving metals with electron beams or etching them with acid.   view more (2008-07-01)

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells
