Chemical Interactions With Cell Membranes Can Be Changed With Modifications Of A Nanoparticle
2013-01-24 14:42:12

Syracuse University Researchers at Syracuse University´s Department of Biomedical and Chemical Engineering at L.C. Smith College of Engineering and Computer Science are studying the toxicity of commonly used nanoparticles, particles up to one million times smaller than a millimeter that could potentially penetrate and damage cell membranes. In a recent article published along with cover art in the leading journal Langmuir entitled “Effects of nanoparticle charge and shape...

Optical Materials Express paper details new laser technique with applications in sensing, photovoltaics, optical switches Silica microwires are the tiny and as-yet underutilized cousins of optical fibers. If precisely manufactured, however, these hair-like slivers of silica could enable applications and technology not currently possible with comparatively bulky optical fiber. By carefully controlling the shape of water droplets with an ultraviolet laser, a team of researchers from...

How Scientists Are Using Silicon To Produce Hydrogen On Demand
2013-01-22 15:30:46

University at Buffalo New technology could help power portable devices like satellite phones and radios Super-small particles of silicon react with water to produce hydrogen almost instantaneously, according to University at Buffalo researchers. In a series of experiments, the scientists created spherical silicon particles about 10 nanometers in diameter. When combined with water, these particles reacted to form silicic acid (a nontoxic byproduct) and hydrogen – a potential...

Gold Nanoparticle Tricks Lymphoma Cancer Cell And Then Kills It

April Flowers for redOrbit.com - Your Universe Online Is it possible to annihilate lymphoma without the use of chemotherapy drugs? Researchers at Northwestern University Feinberg School of Medicine say yes, by starving it of its favorite food: HDL cholesterol. They have discovered a new nanoparticle that acts as a secret double agent, appearing to the cancerous lymphoma cell like natural HDL. When the cell engages with the particle, the particle blocks cholesterol from entering,...

Rice University researchers show short laser pulses selectively heat gold nanoparticles Plasmonic gold nanoparticles make pinpoint heating on demand possible. Now Rice University researchers have found a way to selectively heat diverse nanoparticles that could advance their use in medicine and industry. Rice scientists led by Dmitri Lapotko and Ekaterina Lukianova-Hleb showed common gold nanoparticles, known since the 19th century as gold colloids, heat up at near-infrared wavelengths...

By showing that tiny particles injected into a liquid crystal medium adhere to existing mathematical theorems, physicists at the University of Colorado Boulder have opened the door for the creation of a host of new materials with properties that do not exist in nature. The findings show that researchers can create a "recipe book" to build new materials of sorts using topology, a major mathematical field that describes the properties that do not change when an object is stretched, bent or...

New Metamaterials Produced By Combining Synthetic And Biological Nanoparticles
2012-12-19 16:43:24

Aalto University Scientists from Aalto University, Finland, have succeeded in organizing virus particles, protein cages and nanoparticles into crystalline materials. These nanomaterials studied by the Finnish research group are important for applications in sensing, optics, electronics and drug delivery. Layer structures, or superlattices, of crystalline nanoparticles have been extensively studied in recent years. The research develops hierarchically structured nanomaterials with...

Professor finds roundworm eating fungus could also be a cancer fighter Arthrobotrys oligospora doesn't live a charmed life; it survives on a diet of roundworm. But a discovery by a team led by Mingjun Zhang, an associate professor of biomedical engineering at the University of Tennessee, Knoxville, could give the fungus's life more purpose–as a cancer fighter. Zhang and his team have discovered that nanoparticles produced by A. oligospora hold promise for stimulating the immune...
