Proofreading and error-correction in nanomaterials inspired by nature
Mimicking nature, a procedure developed by researchers at the University of Illinois at Urbana-Champaign can find and correct defects in self-assembled nanomaterials. view more (2005-10-19)
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)
Novel lipoplex nanoparticle to be used in 1st human trial treating advanced solid cancer
The first clinical trial of a biologic nanoparticle designed to give back to cancer patients the tumor-busting gene they have lost is expected to start in September at Georgetown University Medical Center. view more (2005-08-25)
Gold nanoparticles could improve antisense cancer drugs
In the fight against cancer, antisense drugs, which prevent genes from producing harmful proteins such as those that cause cancer, have the promise to be more effective than conventional drugs, but the pace of development of these new drugs has been slow. view more (2006-05-19)
Clemson bioengineer uses nanoparticles to target drugs
Clemson bioengineer Frank Alexis is designing new ways to target drugs and reduce the chances for side effects. view more (2009-10-09)
Homing nanoparticles pack multiple assault on tumors
A collaborative team led by Erkki Ruoslahti, M.D., Ph.D., of the Burnham Institute for Medical Research at UC Santa Barbara (Burnham) has developed nanoparticles that seek out tumors and bind to their blood vessels, and then attract more nanoparticles to the tumor target. view more (2007-01-09)
Targeted nanoparticles incorporating siRNA offer promise for cancer treatment
The use of targeted nanoparticles offers promising techniques for cancer treatment. Researchers in the laboratory of Mark E. Davis at the California Institute of Technology have been using small interfering RNA (siRNA), sometimes known as silencing RNA, to "silence" specific genes that are implicated in certain malignancies. view more (2007-05-21)
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)
Cool! Nanoparticle research points to energy savings
Adding just the right dash of nanoparticles to standard mixes of lubricants and refrigerants could yield the equivalent of an energy-saving chill pill for factories, hospitals, ships, and others with large cooling systems, suggest the latest results from National Institute of Standards and Technology (NIST) research that is pursuing promising... view more...

Scientists meet to discuss health implications of nanoparticles
The possible health implications of nanoparticles will be discussed at a major academic conference, Nanotox 2004, taking place at the Daresbury Laboratories in Cheshire, UK, next week on Tuesday 13th and Wednesday 14th January. Nanotox 2004 is organised jointly by the Royal Microscopical Society and the Electron Microscopy and Analysis Group... view more... (2004-01-07)
Developing a modular, nanoparticle drug delivery system
There are two aspects to creating an effective drug: finding a chemical compound that has the desired biological effect and minimal side-effects and then delivering it to the right place in the body for it to do its job. view more (2007-10-08)
Intravenous nanoparticle gene therapy shows activity in stage IV lung cancer
A cancer-suppressing gene has been successfully delivered into the tumors of stage 4 lung cancer patients via an intravenously administered lipid nanoparticle in a phase I clinical trial at The University of Texas M. D. Anderson Cancer Center. view more (2007-04-18)
Trojan horse for ovarian cancer -- nanoparticles turn immune system soldiers against tumor cells
In a feat of trickery, Dartmouth Medical School immunologists have devised a Trojan horse to help overcome ovarian cancer, unleashing a surprise killer in the surroundings of a hard-to-treat tumor. view more (2009-07-16)
Gold Nanoparticles Emit Intense Heat, Study Finds
Nanoparticles of gold can act as tiny, precise and powerful heaters, which potentially could be used in biomedical applications, according to a new study. view more (2006-03-31)
Research advances on nanotech workplace health and safety
"Companies, workers and investors alike are being challenged by the uncertainties surrounding nanotechnology workplace safety. These uncertainties include lack of sound, scientific information on occupational risks, poorly determined perceptual risks, and hesitancy over nanotechnology oversight," according to co-authors Andrew Maynard... view more...

Berkeley Researchers Find New Route to Nano Self-Assembly
If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) who have found a simple and yet powerfully robust way to induce... view more...

Rice University researchers create 'nanorice'
Who better to invent "nanorice" than researchers at Rice University? But marketing and whimsy weren't what motivated the team of engineers, physicists and chemists from Rice's Laboratory for Nanophotonics (LANP) to make rice-shaped particles of gold and iron oxide. view more (2006-03-15)
MIT researchers make carbon nanotubes without metal catalyst
Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. view more (2009-08-11)
Dual gene therapy suppresses lung cancer in preclinical test
Combination gene therapy delivered in lipid-based nanoparticles drastically reduces the number and size of human non-small cell lung cancer tumors in mice. view more (2007-01-15)
When nano may not be nano
The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health. view more (2009-09-14)
