Nanoparticle News and Research

RSS

In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Nanotechnology holds promise for developing surgical measures

A new review published in WIREs Nanomedicine and Nanobiotechnology explores how nanotechnology may provide powerful new tools that could have a marked impact on the therapeutic and diagnostic measures available to surgeons.

Silver nanoparticle coated 'killer paper' for food packaging

Scientists are reporting development and successful lab tests of "killer paper," a material intended for use as a new food packaging material that helps preserve foods by fighting the bacteria that cause spoilage. The paper, described in ACS's journal, Langmuir, contains a coating of silver nanoparticles, which are powerful anti-bacterial agents.

Researchers design nanoparticles that make blood clots visible to CT scanner

For almost two decades, cardiologists have searched for ways to see dangerous blood clots before they cause heart attacks. Now, researchers at Washington University School of Medicine in St. Louis report that they have designed nanoparticles that find clots and make them visible to a new kind of X-ray technology.

Nanosilver used in medications as early as 1889

Nanosilver is not a new discovery by nanotechnologists - it has been used in various products for over a hundred years, as is shown by a new Empa study. The antimicrobial effects of minute silver particles, which were then known as "colloidal silver", were known from the earliest days of its use.

Silicon dioxide coated rust nanoparticles to fight cervical cancer

The next big thing in medical diagnostics could be minutes particles of rust, iron oxide, coated with the material from which sand is formed, silicon dioxide. These magnetic nanoparticles, a mere 29 to 230 nanometers across, can be used to trap antibodies to the virus that causes cervical cancer and to the bacteria that causes potentially lethal diarrhea.

Magnetic nanoparticles for ovarian cancer treatment

A paper published in the January issue of the journal Nanomedicine could provide the foundation for a new ovarian cancer treatment option - one that would use an outside-the-body filtration device to remove a large portion of the free-floating cancer cells that often create secondary tumors.

Findings could speed use of RNA nanotechnology for treating disease

Scientists are reporting an advance in overcoming a major barrier to the use of the genetic material RNA in nanotechnology - the field that involves building machines thousands of times smaller than the width of a human hair and now is dominated by its cousin, DNA. Their findings, which could speed the use of RNA nanotechnology for treating disease, appear in the monthly journal ACS Nano.
