A new metal nanostructure developed by researchers at the University of California, Santa Cruz, has already shown promise in cancer therapy studies and could be used for chemical and biological sensors and other applications as well. view more (2009-03-23)
Fluorescent proteins illuminating biomedical research
Remarkable new tools that spotlight individual cellular molecules are transforming biomedical research. Scientists at the Gruss Lipper Biophotonics Center at the Albert Einstein College of Medicine of Yeshiva University have spearheaded their use in a series of papers, including one published today in the online version of Nature Methods. view more (2009-01-26)
Between water and rock -- a new science
Water chemistry and mineralogy are scientific fields that have been around long enough to develop extensive knowledge and technologies. The boundary of water and rock, however, is not a thin wet line but the huge new field of nanoparticle science. view more (2007-12-03)
Glowing Results-Pitt Researchers Use Fluorescence to Develop Fast, Simple Method for Detecting Mercury in Fish and Dental Fillings
Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. view more (2008-11-19)
Researchers make synthetic DNA 'barcodes' to tag pathogens, providing an inexpensive, off-the-shelf monitoring system
A supermarket checkout computer can identify thousands of different items by scanning the tiny barcode printed on the package. New technology developed at Cornell University could make it just as easy to identify genes, pathogens, illegal drugs and other chemicals of interest by tagging them with color-coded probes made out of synthetic... view more...

Gene that magnetically labels cells shows potential as imaging tool
Mammalian cells can produce tiny magnetic nuggets after the introduction of a single gene from bacteria, scientists have found. The gene MagA could become a valuable tool for tracking cells' movement through the body via magnetic resonance imaging (MRI), says Xiaoping Hu, PhD, professor of biomedical engineering at Emory University and the Georgia... view more...

Nanotech: Unpredictable And Un-Regulated - New Report From ETC Group
The ETC Group releases a new Communiqué today that provides an update on policy discussions related to nanotech health and safety issues and the glaring lack of regulatory oversight. According to the ETC Group, governments on both sides of the Atlantic are reluctantly and belatedly conceding that current safety and health regulations may... view more... (2004-07-09)
Nanocoating could eliminate foggy windows and lenses
Foggy windows and lenses are a nuisance, and in the case of automobile windows, can pose a driving hazard. view more (2005-08-29)
Manufactured Buckyballs don't harm microbes that clean the environment
Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment, according to Purdue University researchers. view more (2008-04-09)
New GM mosquito sexing technique is step towards malaria control, report scientists
Scientists have genetically modified male mosquitoes to express a glowing protein in their gonads, in an advance that allows them to separate the different sexes quickly. view more (2005-10-10)
New light-emitting biomaterial could improve tumor imaging, study shows
A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. view more (2009-08-11)
New nanoparticle vaccine is more effective but less expensive
Good news for public health: Bioengineering researchers from the EPFL in Lausanne, Switzerland, have developed and patented a nanoparticle that can deliver vaccines more effectively, with fewer side effects, and at a fraction of the cost of current vaccine technologies. view more (2007-09-17)
UNC study: shape, not just size, impacts effectiveness of emerging nanomedicine therapies
In the budding field of nanotechnology, scientists already know that size does matter. But now, researchers at the University of North Carolina at Chapel Hill have shown that shape matters even more - a finding that could lead to new and more effective methods for treating cancer and other diseases, from diabetes and multiple sclerosis to... view more...

Purifying nanorods: Big success with tiny cleanup
Chemists at Rice University have discovered a novel method to produce ultra-pure gold nanorods -- tiny, wand-like nanoparticles that are being studied in dozens of labs worldwide for applications as broad as diagnosing disease and improving electronic viewscreens. view more (2008-09-23)
Faster, more cost-effective DNA test for crime scenes, disease diagnosis
Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction (PCR) a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. view more (2009-07-09)
One nano-step closer to weighing a single atom
By studying gold nanoparticles with highly uniform sizes and shapes, scientists now understand how they lose energy, a key step towards producing nanoscale detectors for weighing any single atom. view more (2009-07-28)
Case Western Reserve researchers develop 'wireless' activation of brain circuits
Traditionally, stimulating nerves or brain tissue involves cumbersome wiring and a sharp metal electrode. But a team of researchers at Case Western Reserve University is going "wireless." view more (2009-02-24)
MIT sorts cells with beams of light
Separating out particular kinds of cells from a sample could become faster, cheaper and easier thanks to a new system developed by MIT researchers that involves levitating the cells with light. view more (2007-12-11)
Buckyballs could keep water systems flowing
Microscopic particles of carbon known as buckyballs may be able to keep the nation's water pipes clear in the same way clot-busting drugs prevent arteries from clogging up. view more (2009-03-05)
