Scientists discover how gold eases pain of arthritis
Scientists at Duke University Medical Center may have solved the mystery surrounding the healing properties of gold - a discovery they say may renew interest in gold salts as a treatment for rheumatoid arthritis and other inflammatory diseases. view more (2007-10-23)
When gold becomes a catalyst
Gold has always been perceived as a precious material: you win a gold medal when you prove to be the best in a competition; you only get a Gold credit card when you are a preferential customer, and the jewelry made of this material is amongst the most valuable. view more (2006-06-23)
Widely used iron nanoparticles exhibit toxic effects on neuronal cells
Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions. view more (2007-03-29)
Nano-sized technology has super-sized effect on tumors
Anyone facing chemotherapy would welcome an advance promising to dramatically reduce their dose of these often harsh drugs. Using nanotechnology, researchers at Washington University School of Medicine in St. Louis have taken a step closer to that goal. view more (2008-04-03)
Under magnetic force, nanoparticles may deliver gene therapy
After binding DNA segments to tiny iron-containing spheres called nanoparticles, researchers have used magnetic fields to direct the nanoparticles into arterial muscle cells, where the DNA could have a therapeutic effect. view more (2007-08-01)
Research could help finger more criminals
Scientists at the University of Sunderland are working on new technology that could help police forces catch criminals, by providing more clear and detailed fingerprints. Researchers at the university's School of Health, Natural & Social Sciences are developing what's known as a nanoparticle suspension, which could be a major breakthrough for... view more...

Brown Chemists Create Cancer-Detecting Nanoparticles
A team led by a Brown University chemist has created the smallest iron oxide nanoparticles to date for cancer detection by magnetic resonance imaging (MRI). The magnetic nanoparticles operate like tiny guided missiles, seeking and attaching themselves to malignant tumor cells. Once they bind, the particles emit stronger signals that MRI scans can... view more... (2008-05-28)
Cancer drug delivery research at Case Western Reserve University cuts time from days to hours
Researchers at Case Western Reserve University have developed a technique that has the potential to deliver cancer-fighting drugs to diseased areas within hours, as opposed to the two days it currently takes for existing delivery systems. view more (2008-07-23)
Adenine 'tails' make tailored anchors for DNA
Researchers from the National Institute of Standards and Technology (NIST), the Naval Research Laboratory (NRL) and the University of Maryland (UMD) have demonstrated a deceptively simple technique for chemically bonding single strands of DNA to gold. view more (2006-12-27)
Hygienic surfaces, biocidal and self-cleaning coatings
Microbian evolution on a wide variety of surfaces can produce phenomena such as corrosion, dirt, smells and even serious hygiene and health problems. view more (2005-09-14)
Nanotech protection
Writing in a forthcoming issue of the International Journal of Nanotechnology, Canadian engineers suggest that research is needed into the risks associated with the growing field of nanotechnology manufacture so that appropriate protective equipment can be developed urgently. view more (2009-10-14)
All done with mirrors: NIST microscope tracks nanoparticles in 3-D
A clever new microscope design allows nanotechnology researchers at the National Institute of Standards and Technology (NIST) to track the motions of nanoparticles in solution as they dart around in three dimensions. view more (2008-03-11)
Therapeutic nanoparticles give new meaning to sugar-coating medicine
A research team at the National Institute of Standards and Technology (NIST) studying sugar-coated nanoparticles for use as a possible cancer therapy has uncovered a delicate balancing act that makes the particles more effective than conventional thinking says they should be. view more (2009-09-23)
Nanogenerators convert mechanical energy to electricity for self-powered devices
Researchers have developed a new technique for powering nanometer-scale devices without the need for bulky energy sources such as batteries. view more (2006-04-14)
Safer nanoparticles spotlight tumors, deliver drugs
Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now a team of scientists has created miniscule flakes of silicon that glow brightly, last long enough to slowly release cancer drugs, then break down into harmless by-products. view more (2009-02-23)
Topical erectile dysfunction therapy shows promise
An innovative drug-delivery system - nanoparticles encapsulating nitric oxide or prescription drugs - shows promise for topical treatment of erectile dysfunction (ED), according to a new study by scientists at Albert Einstein College of Medicine of Yeshiva University. view more (2009-09-21)
