Using Life's Building Blocks to Control Nanoparticle Assembly
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters. view more (2007-08-23)
Cutaneous application of nanoparticles offers hope for treatment of erectile dysfunction
Cutaneous application of nanoparticles may offer a new means of delivering drugs to treat erectile dysfunction (ED), according to findings presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA). view more (2009-04-27)
Nano-sized 'trojan horse' to aid nutrition
Researchers from Monash University have designed a nano-sized "trojan horse" particle to ensure healing antioxidants can be better absorbed by the human body. view more (2008-08-25)

It may sound counterintuitive to use a microbial protein to improve water quality. view more (2007-06-18)
Scientists design simple dipstick test for cocaine, other drugs
Researchers at the University of Illinois at Urbana-Champaign have developed a simple "dipstick" test for detecting cocaine and other drugs in saliva, urine or blood serum. view more (2006-11-14)
UCF Nanoparticle Offers Promise for Treating Glaucoma
A unique nanoparticle made in a laboratory at the University of Central Florida is proving promising as a drug delivery device for treating glaucoma, an eye disease that can cause blindness and affects millions of people worldwide. view more (2007-06-19)
Failed HIV Drug Gets Second Chance with Addition of Gold Nanoparticles
Researchers at North Carolina State University have discovered that adding tiny bits of gold to a failed HIV drug rekindle the drug's ability to stop the virus from invading the body's immune system. view more (2008-05-27)
Bio-inspired assembly of nanoparticle building blocks
Chemists at Rice University have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature's oldest known chemical innovations - the self-assembly of lipid membranes that surround every living cell. view more (2006-11-28)
Nanoparticle-delivered 'suicide' genes slowed ovarian tumor growth
Nanoparticle delivery of diphtheria toxin-encoding DNA selectively expressed in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect this therapy could be tested in humans within 18 to 24 months, according to a report in Cancer Research, a journal of the American Association for Cancer Research. view more (2009-07-30)
Nanoparticles trigger cell death?
Nanoparticles that are one milliard of a metre in size are widely used, for example, in cosmetics and food packaging materials. view more (2008-11-13)
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)
Novel approach estimates nanoparticles in environment
Without knowing how much of an industrial chemical is being produced, it is almost impossible for scientists to determine if it poses any threat to the environment or human health. view more (2009-05-21)
Nanoparticle Could Help Detect Many Diseases Early
Most people think of hydrogen peroxide as a topical germ killer, but the medicine cabinet staple is gaining steam in the medical community as an early indicator of disease in the body. view more (2007-08-21)
Truly sick or simply scared?
Scientists at Pacific Northwest National Laboratory have discovered a way to increase the sensitivity of test strips that will enable creation of a portable biosensor that can address a major concern associated with incidents involving chemical or nerve agents - the need to quickly distinguish between individuals who have been exposed and the... view more...

A new 'Pyrex' nanoparticle
Researchers in Switzerland have developed a new method to fabricate borosilicate glass nanoparticles. Used in microfluidic systems, these "Pyrex"-like nanoparticles are more stable when subjected to temperature fluctuations and harsh chemical environments than currently used nanoparticles made of polymers or silica glass. view more (2008-09-08)
First direct electric link between neurons and light-sensitive nanoparticle films created
The world's first direct electrical link between nerve cells and photovoltaic nanoparticle films has been achieved by researchers at the University of Texas Medical Branch at Galveston (UTMB) and the University of Michigan. view more (2007-02-28)
Synthetic HDL: A new weapon to fight cholesterol problems
Buttery Christmas cookies, eggnog, juicy beef roast, rich gravy and creamy New York-style cheesecake. Happy holiday food unfortunately can send blood cholesterol levels sky high. view more (2009-01-12)
As nanotech goes mainstream, 'toxic socks' raise concerns
Nanotechnology is now available in a store near you. Valued for it's antibacterial and odor-fighting properties, nanoparticle silver is becoming the star attraction in a range of products from socks to bandages to washing machines. But as silver's benefits propel it to the forefront of consumer nanomaterials, scientists are recommending a closer... view more... (2008-04-07)
Nanoparticles carry cancer-killing drugs into tumor cells
University of Michigan scientists have created the nanotechnology equivalent of a Trojan horse to smuggle a powerful chemotherapeutic drug inside tumor cells - increasing the drug's cancer-killing activity and reducing its toxic side effects. view more (2005-06-15)
Nanoparticles can track cells deep within living organisms
To the delight of researchers at Washington University School of Medicine in St. Louis, living cells gobbled up fluorine-laced nanoparticles without needing any coaxing. Then, because of the unusual meal, the cells were easily located with MRI scanning after being injected into mice. view more (2007-03-27)
