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)
Bacteria ferry nanoparticles into cells for early diagnosis, treatment
Researchers at Purdue University have shown that common bacteria can deliver a valuable cargo of "smart nanoparticles" into a cell to precisely position sensors, drugs or DNA for the early diagnosis and treatment of various diseases. view more (2007-06-14)
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)
Hollow gold nanospheres show promise for biomedical and other applications
A new metal nanostructure developed by researchers at the University of California, Santa Cruz, has already shown promise in cancer therapy studies and could be used for chemical and biological sensors and other applications as well. view more (2009-03-23)
Targeted nanospheres find, penetrate, then fuel burning of melanoma
Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research. view more (2009-02-02)
Between water and rock -- a new science
Water chemistry and mineralogy are scientific fields that have been around long enough to develop extensive knowledge and technologies. The boundary of water and rock, however, is not a thin wet line but the huge new field of nanoparticle science. view more (2007-12-03)
Using Nanoparticles, In Vivo Gene Therapy Activates Brain Stem Cells
Using customized nanoparticles that they developed, University at Buffalo scientists have for the first time delivered genes into the brains of living mice with an efficiency that is similar to, or better than, viral vectors and with no observable toxic effect, according to a paper published this week in Proceedings of the National Academy of... view more...

Nanotech: Unpredictable And Un-Regulated - New Report From ETC Group
The ETC Group releases a new Communiqué today that provides an update on policy discussions related to nanotech health and safety issues and the glaring lack of regulatory oversight. According to the ETC Group, governments on both sides of the Atlantic are reluctantly and belatedly conceding that current safety and health regulations may... view more... (2004-07-09)
Nanocoating could eliminate foggy windows and lenses
Foggy windows and lenses are a nuisance, and in the case of automobile windows, can pose a driving hazard. view more (2005-08-29)
Manufactured Buckyballs don't harm microbes that clean the environment
Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment, according to Purdue University researchers. view more (2008-04-09)
New nanoparticle vaccine is more effective but less expensive
Good news for public health: Bioengineering researchers from the EPFL in Lausanne, Switzerland, have developed and patented a nanoparticle that can deliver vaccines more effectively, with fewer side effects, and at a fraction of the cost of current vaccine technologies. view more (2007-09-17)
UNC study: shape, not just size, impacts effectiveness of emerging nanomedicine therapies
In the budding field of nanotechnology, scientists already know that size does matter. But now, researchers at the University of North Carolina at Chapel Hill have shown that shape matters even more - a finding that could lead to new and more effective methods for treating cancer and other diseases, from diabetes and multiple sclerosis to... view more...

Purifying nanorods: Big success with tiny cleanup
Chemists at Rice University have discovered a novel method to produce ultra-pure gold nanorods -- tiny, wand-like nanoparticles that are being studied in dozens of labs worldwide for applications as broad as diagnosing disease and improving electronic viewscreens. view more (2008-09-23)
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)
Case Western Reserve researchers develop 'wireless' activation of brain circuits
Traditionally, stimulating nerves or brain tissue involves cumbersome wiring and a sharp metal electrode. But a team of researchers at Case Western Reserve University is going "wireless." view more (2009-02-24)
Buckyballs could keep water systems flowing
Microscopic particles of carbon known as buckyballs may be able to keep the nation's water pipes clear in the same way clot-busting drugs prevent arteries from clogging up. view more (2009-03-05)
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)
Identifying proteins with new microchip surfaces. Protein-binding nanoparticles simplify MALDI-TOF mass spectrometry
How does life function? In biology today, this is the question about the interplay between the countless molecules that make up all life forms. For example, if the interactions of proteins are interfered with, this can be a cause of illnesses. Nowadays, bio-chips are being used to an increasing extent to research these molecular interactions.... view more... (2003-08-06)
Buckyballs boost antibody's chemotherapy payload
In the ongoing search for better ways to target anticancer drugs to kill tumors without making people sick, researchers find that nanoparticles called buckyballs might be used to significantly boost the payload of drugs carried by tumor-targeting antibodies. view more (2006-06-22)
Jefferson scientists deliver toxic genes to effectively kill pancreatic cancer cells
A research team, led by investigators at the Department of Surgery at Jefferson Medical College of Thomas Jefferson University and the Kimmel Cancer Center at Jefferson, has achieved a substantial "kill" of pancreatic cancer cells by using nanoparticles to successfully deliver a deadly diphtheria toxin gene. view more (2008-09-24)
