Gold nanorods shed light on new approach to fighting cancer
Researchers have shown how tiny "nanorods" of gold can be triggered by a laser beam to blast holes in the membranes of tumor cells, setting in motion a complex biochemical mechanism that leads to a tumor cell's self-destruction. view more (2007-10-17)
Magnetic nano-'shepherds' organize cells
The power of magnetism could be an enabling technology to address a major problem facing bioengineers as they try to create new tissue-getting human cells to not only form structures, but to stimulate the growth of blood vessels to nourish their growth. view more (2009-04-01)
New silver nanoparticle skin gel for healing burns
Scientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. With names like silver sulfadiazine and silver nitrate, these germ-fighters save lives and speed healing. view more (2009-07-23)
NIST reference materials are 'gold standard' for bio-nanotech research
The National Institute of Standards and Technology (NIST) has issued its first reference standards for nanoscale particles targeted for the biomedical research community-literally "gold standards" for labs studying the biological effects of nanoparticles. view more (2008-01-10)
Test finds manufactured nanoparticles don't harm soil ecology
The first published study on the environmental impact of manufactured nanoparticles on ordinary soil showed no negative effects, which is contrary to concerns voiced by some that the microscopic particles could be harmful to organisms. view more (2007-03-23)
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...

Sea Coral's Trick Helps Scientists Tag Proteins
The glow emitted by a variety of sea coral helped Russian scientists harness the protein that generates the light to create a tiny fluorescent tag that responds to visible light. view more (2006-03-20)
New Methods for Screening Nanoparticles
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles - particles with dimensions on the order of billionths of a meter - interact with human cells following exposure for various times and doses. view more (2006-08-22)
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)
Implant bacteria, beware: Researchers create nano-sized assassins
Staphylococcus epidermidis is quite an opportunist. Commonly found on human skin, the bacteria pose little danger. But S. epidermidis is a leading cause of infections in hospitals. view more (2009-06-26)
Metals Shape Up with a Little Help from Friends
For 5,000 years the only way to shape metal has been by the "heat and beat" technique. Even with modern nanotechnology, metalworking involves carving metals with electron beams or etching them with acid. view more (2008-07-01)
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)
Singapore scientists synthesize gold to shed light on cells' inner workings
Highly fluorescent gold nanoclusters for sub-cellular imaging have been synthesized by researchers at the Institute of Bioengineering and Nanotechnology (IBN). view more (2009-04-16)
In Nature, Proteins Sweep up Nanoparticles
Here's a pollution-control tip from nature: Deep inside a flooded mine in Wisconsin, scientists from several institutions including the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a world in which bacteria emit proteins that sweep up metal nanoparticles into immobile clumps. view more (2007-06-18)
Using magnetism to turn drugs on and off
Many medical conditions, such as chronic pain, cancer and diabetes, require medications that cannot be taken orally, but must be dosed intermittently, on an as-needed basis, over a long period of time. view more (2009-09-21)
Fluorescent cancer cells to guide brain surgeons
Gliomas are malignant brain tumors that arise from glial (supporting) cells of the brain. Gliomas are often resistant to chemotherapy. view more (2009-04-06)
Quantum dots reviewed — Could these nanoparticles hold the cure to cancer?
The worlds of medical and biological research are abuzz with the promises offered by nanoparticles known as semiconductor quantum dots. These Quantum Dots (QDs) have unique optical and electronic properties that make them suitable for breakthrough treatments such as the detection and destruction of cancer cells. view more (2006-09-15)
Conference report highlights new research into drug delivery to treat eye disease
Researchers are investigating microneedles, nanoparticles and polymer carriers as potential new techniques to combat the leading cause of visual impairment and blindness in the United States, according to a report from the Third Annual ARVO/Pfizer Ophthalmics Research Institute Conference. view more (2008-11-18)
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)
