A whole new class of biosensor that can detect exceptionally small traces of contaminants in liquids in just 40 minutes has been developed by a UNSW-led team of researchers. Known as a biochemiresistor, it meets a long-standing challenge to create a sensor that is not only super-sensitive to the presence of chemical compounds but responds quickly. It has countless potential uses for detecting drugs, toxins and pesticides for biomedical or environmental analysis. In a paper published in...

Medical uses for quantum dots -- tiny luminescent crystals -- could include image-guided surgery, light-activated therapies and sensitive diagnostic tests A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine. The research, which will appear on May 20 in Nature Nanotechnology online, is likely the...

Breathalyzer Reveals Signs Of Disease

[ Watch the Video ] One exhale and new device could screen for everything from diabetes to lung cancer This invention could give new meaning to the term "bad breath!" It's the Single Breath Disease Diagnostics Breathalyzer, and when you blow into it, you get tested for a biomarker–a sign of disease. As amazing as that sounds, the process is actually very simple thanks to ceramics nanotechnology. All it takes is a single exhale. You blow into a small valve attached to a box that...

New Research Uses Nanoparticles to Deliver Antibiotics to Beneficial Bacteria
2012-05-07 04:52:13

Connie K. Ho for RedOrbit.com Researchers at the Massachusetts Institute of Technology (MIT) and Brigham and Women´s Hospital, a teaching affiliate of Harvard Medical School, recently released information that they have studied a nanoparticle to help the immune system. The nanoparticle can focus on particular infection sites with specific antibiotics. The study is published in the journal American Chemical Society´s journal ACS Nano. According to Aleks Radovic-Moreno, a MIT...

Current nanomedicine research has focused on the delivery of established and novel therapeutics. But a UNC team is taking a different approach. They developed nanoparticle carriers to successfully deliver therapeutic doses of a cancer drug that had previously failed clinical development due to pharmacologic challenges. They report their proof of principle findings in the April 30, 2012 early online edition of Proceedings of the National Academy of Sciences. Wortmannin is a drug that was...

'A huge step forward in the safety screening of nanomaterials,' researchers say Engineered nanomaterials, prized for their unique semiconducting properties, are already prevalent in everyday consumer products – from sunscreens, cosmetics and paints to textiles and solar batteries – and economic forecasters are predicting the industry will grow into $1 trillion business in the next few years. But how safe are these materials? Because the semiconductor properties of...

A recent paper by Kathleen Eggleson, a research scientist in the Center for Nano Science and Technology (NDnano) at the University of Notre Dame, provides an example of a nanotechnology-related safety and ethics problem that is unfolding right now. The world of nanotechnology, which involves science and engineering down at billionths-of-a-meter scales, might seem remote. But like most new advances, the application of that technology to everyday experience has implications that can...

The new drugs would be more effective and with fewer side effects Researchers from the Research Programme in Biomedical Informatics (GRIB) from the IMIM (Hospital del Mar Research Institute) and the Pompeu Fabra University (UPF) have identified 115 proteins in silico (via computer simulation) that could be highly relevant to treat colon-rectal cancer, since they would make it possible to define the strategy to design new generation anti-cancer drugs. During the last years, it has been...

A team of scientists from Johns Hopkins and elsewhere have developed nano-devices that  successfully cross the brain-blood barrier and deliver a drug that tames brain-damaging inflammation in rabbits with cerebral palsy. A report on the experiments, conducted at Wayne State University in collaboration with the Perinatology Research Branch of the National Institute of Child Health and Human Development, before the lead and senior investigators moved to Johns Hopkins, is published in...

Combining two strategies designed to improve the results of cancer treatment — antiangiogenesis drugs and nanomedicines — may only be successful if the smallest nanomedicines are used. A new study from Massachusetts General Hospital (MGH) researchers, appearing in Nature Nanotechnology, finds that normalizing blood vessels within tumors, which improves the delivery of standard chemotherapy drugs, can block the delivery of larger nanotherapy molecules. "We found that vascular...


Word of the Day
siliqua
  • A Roman unit of weight, 1⁄1728 of a pound.
  • A weight of four grains used in weighing gold and precious stones; a carat.
  • In anatomy, a formation suggesting a husk or pod.
  • The lowest unit in the Roman coinage, the twenty-fourth part of a solidus.
