Max Planck researchers channel microcapsules into tumour cells and release their contents using a laser impulse
Treating malignant tumours is difficult. Doctors have to destroy the tumour, but healthy tissue needs to be preserved. Chemotherapy tends to kill diseased cells, at the same time causing great damage to the body in general.   view more (2006-08-24)

Nonstick and laser-safe gold aids laser trapping of biomolecules
Biophysicists long for an ideal material-something more structured and less sticky than a standard glass surface-to anchor and position individual biomolecules.   view more (2009-06-18)

Mayo Clinic study explores link between nanoparticles and kidney stones
Researchers at Mayo Clinic have successfully isolated nanoparticles from human kidney stones in cell cultures and have isolated proteins, RNA and DNA that appear to be associated with nanoparticles.   view more (2006-12-20)

Researchers probe health and safety impacts of nanotechnology
University of Florida engineering student Maria Palazuelos is working on nanotechnology, but she's not seeking a better sunscreen, tougher golf club or other product — the focus of many engineers in the field.   view more (2007-01-31)

The nanoworld of corrosion
The effect of corrosion has an impact on about 3% of the world's Gross Domestic Product. From a positive point of view, however, chemical attack of metal surfaces may result into surface nano-structures with very interesting technological applications such as catalysts and sensors.   view more (2006-02-10)

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)

Nano-scale trees created at Lund Institute of Technology
For the last few years scientists at the Nanometer Consortium at Lund University have been able to make nanowires, tiny wires just a few millionths of a millimeter "thick" and made of semiconducting material of great potential in the electronics industry. Now they have managed to produce "nanotrees," in fact tiny forests on the... view more... (2004-05-05)

UCLA researchers develop new nanomaterials to deliver anti-cancer drugs to cells
Researchers at UCLA have successfully manipulated nanomaterials to create a new drug-delivery system that promises to solve the challenge of the poor water solubility of today's most promising anticancer drugs and thereby increase their effectiveness.   view more (2007-06-08)

New technique sees into tissue at greater depth, resolution
By coupling a kicked-up version of microscopy with miniscule particles of gold, Duke University scientists are now able to peer so deep into living tissue that they can see molecules interacting.   view more (2008-09-18)

Repetitive motion speeds nanoparticle uptake
Newly published research by Rice University chemists and North Carolina State University toxicologists finds that repetitive movement can speed the uptake of nanoparticles through the skin.   view more (2007-01-05)

Research measures movement of nanomaterials in simple model food chain
New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms.   view more (2008-06-02)

'Custom' nanoparticles could improve cancer diagnosis and treatment
Researchers have developed "custom" nanoparticles that show promise of providing a more targeted and effective delivery of anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles.   view more (2006-03-27)

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells
A team of Iowa State University plant scientists and materials chemists have successfully used nanotechnology to penetrate plant cell walls and simultaneously deliver a gene and a chemical that triggers its expression with controlled precision.   view more (2007-05-17)

MIT, Brigham: Nanoparticles armed to combat cancer
Ultra-small particles loaded with medicine-and aimed with the precision of a rifle-are offering a promising new way to strike at cancer, according to researchers working at MIT and Brigham and Women's Hospital.   view more (2006-04-11)

Argonne scientists discover networks of metal nanoparticles are culprits in alloy corrosion
Oxide scales are supposed to protect alloys from extensive corrosion, but scientists at U.S. Department of Energy's Argonne National Laboratory have discovered metal nanoparticle chinks in this armor.   view more (2008-08-05)

Magnetic nanoparticles to simultaneously diagnose, monitor and treat
Whether it's magnetic nanoparticles (mNPs) giving an army of 'therapeutically armed' white blood cells direction to invade a deadly tumour's territory, or the use of mNPs to target specific nerve channels and induce nerve-led behaviour (such as the life-dependant thumping of our hearts), mNPs have come a long way in the past decade.   view more (2009-11-06)

UCF technique promises to aid doctor's ability to identify, treat bacterial infections
A new technique developed by a University of Central Florida chemist will help physicians more quickly identify the bacterial infections patients have so they can be treated in hours instead of days.   view more (2008-02-20)

Colorful bacteria more dangerous
A new study in the July 18 issue of The Journal of Experimental Medicine shows that gold-colored bacteria are more harmful than their unpigmented relatives. A group of scientists led by Victor Nizet (UCSD, San Diego, CA) have discovered that the molecules that give certain bugs their color also help them resist attack by immune cells called... view more...

U of T team heats up gold to surprising effect: it gets harder not softer
Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite.   view more (2009-01-23)

Beyond the hype and the scare stories, how safe are nanoparticles?
The May issue of Nano Today (www.nanotoday.com) launches a dedicated forum for debate on the effects of nanoparticles on human health. In "Nanotechnology: assessing the risks", Andrew Maynard of the Woodrow Wilson International Center for Scholars calls for a strategic approach to research on potential risks to ensure the development of... view more...
