A new study by University of Kentucky researchers shows promise for developing ultrastable RNA nanoparticles that may help treat cancer and viral infections by regulating cell function and binding to cancers without harming surrounding tissue. The study, published in Nano Today, was carried out in the laboratory of Peixuan Guo, the William S. Farish Endowed Chair in Nanobiotechnology at the UK Markey Cancer Center, in collaboration with Dr. Mark Evers, director of the UK Markey Cancer...

By modifying the rate at which chemical reactions take place, nanoparticle catalysts fulfill myriad roles in industry, the biomedical arena and everyday life. They may be used for the production of polymers and biofuels, for improving pollution and emission control devices, to enhance reactions essential for fuel cell technology and for the synthesis of new drugs. Finding new and more effective nanoparticle catalysts to perform these useful functions is therefore vital. Now Nongjian (NJ)...

Study says manufactured nanomaterials may be harmful to agricultural production Researchers contend that manufactured nanomaterials--now popular in consumer products such as shampoos, gels, hair dyes and sunscreens--may be detrimental to the quality and yield of food crops, as reported in a paper in the online edition of Proceedings of the National Academy of Sciences. Manufactured nanomaterials are man-made materials produced by manipulating matter on an atomic and molecular scale....

Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing. Those nanoparticles eventually end up in agricultural soil, which is a cause for concern, according to a group of environmental scientists that recently carried out the first major study of soybeans grown in soil contaminated by two manufactured nanomaterials (MNMs). The team was led by scientists at UC Santa Barbara's Bren School of...

DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA’s code can similarly shape metallic structures. The team found that DNA segments can direct the shape of gold nanoparticles – tiny gold crystals that have many applications in medicine, electronics and catalysis. Led by Yi Lu, the Schenck Professor of Chemistry at the U. of I., the team published its surprising findings in the journal Angewandte...

FARMINGTON, Conn., Aug. 6, 2012 /PRNewswire-iReach/ -- New research estimates that worldwide production of nanomaterials increased tenfold to over 270,000 tons between 2002 and 2011. Nanomaterials are sophisticated molecules embedded in thousands of products. Despite potential risks and growing awareness about the safety of nanoparticles ranging from respiratory health to potential impacts on the food chain, the field continues growing at an incredible rate. Nanotechnology applications are...

RED BANK, N.J., Aug. 2, 2012 /PRNewswire/ -- By adding new patents to its original license to Natcore Technology Inc. (TSX-V: NXT; NTCXF.PK), the National Renewable Energy Laboratory (NREL) has expanded that license under which Natcore will develop and commercialize a line of black silicon products based on NREL patents. "Black silicon" refers to the apparent color of the surface of a silicon wafer after it has been etched with nano-scale pores; the black color results from the...
