While attempting to solve one mystery about iron oxide-based nanoparticles, a research team working at the National Institute of Standards and Technology (NIST) stumbled upon another one. But once its implications are understood, their discovery* may give nanotechnologists a new and useful tool. The nanoparticles in question are spheres of magnetite so tiny that a few thousand of them lined up would stretch a hair's width, and they have potential uses both as the basis of better data storage...

--New Delivery Platform May Become a Therapy for Patients with Vascular Disease-- PHILADELPHIA, April 19 /PRNewswire-USNewswire/ -- Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent...

New delivery platform may become a therapy for patients with vascular disease Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy. Conducted in cell cultures and rats, the research is the...

Scientists at the Naval Research Laboratory and the University of Illinois-Urbana Champaign recently reported a new technique for directly writing composites of nanoparticles and polymers. Recent years have seen significant advances in the properties achieved by both these materials, and so researchers have begun to blend these materials into nanocomposites that access the properties of both materials. Forming these nanocomposites into structures has been tricky since each nanocomposite would...

Whether it's magnetic nanoparticles (mNPs) giving an army of 'therapeutically armed' white blood cells direction to invade a deadly tumour's territory, or the use of mNPs to target specific nerve channels and induce nerve-led behaviour (such as the life-dependant thumping of our hearts), mNPs have come a long way in the past decade. The future for mNPs however appears even brighter. With the design of 'theranostic' molecules, mNPs could play a crucial role in developing one-stop tools to...

A research team at the National Institute of Standards and Technology (NIST) studying sugar-coated nanoparticles for use as a possible cancer therapy has uncovered a delicate balancing act that makes the particles more effective than conventional thinking says they should be. Just like individuals in a crowd respecting other people's personal space, the particles work because they get close together, but not too close. In cooperation with colleagues at The Johns Hopkins University, Dartmouth...

 The power of magnetism may 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 that growth.A multidisciplinary team of investigators from Duke University, Case Western Reserve University and the University of Massachusetts, Amherst created an environment where magnetic particles suspended within a specialized solution act like molecular sheep dogs. In...

Chains of 1 million magnetic nanoparticles have been assembled and disassembled in a solution of suspended particles in a controlled way, scientists at the National Institute of Standards and Technology (NIST) report. Such particles and structures, once their properties are more fully understood and can be manipulated reliably, may be useful in applications such as medical imaging and information storage. The NIST work, scheduled to be featured on the cover of an upcoming issue of Langmuir*...

RICHMOND, Va. (Aug. 29, 2005) "“ Virginia Commonwealth University researchers have created highly magnetized nanoparticles based on metallic iron that could one day be used in a non-invasive therapy for cancer in which treatment would begin at the time of detection. "We envision a potential for these materials to combine both detection and treatment into a single process," said Everett E. Carpenter, Ph.D., an assistant professor of chemistry at VCU. Carpenter is discussing his ongoing...
