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.

New nanoparticle can help develop vaccines against HIV, malaria

MIT engineers have designed a new type of nanoparticle that could safely and effectively deliver vaccines for diseases such as HIV and malaria.

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.

FDA approves ultrasmall silica inorganic nanoparticle INDA for targeted molecular imaging of cancer

Researchers at Memorial Sloan-Kettering Cancer Center's Nanotechnology Center, along with collaborators at Cornell University and Hybrid Silica Technologies, have received approval for their first Investigational New Drug Application from the US Food and Drug Administration for an ultrasmall silica inorganic nanoparticle platform for targeted molecular imaging of cancer, which may be useful for cancer treatment in the future.

Warwick research opens new strategy in vehicle design for drug release

The ability of some forms of plankton and bacteria to build an extra natural layer of nanoparticle-like armour has inspired chemists at the University of Warwick to devise a startlingly simple way to give drug bearing polymer vesicles (microscopic polymer based sacs of liquid) their own armoured protection.

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.
