New technique to make gene therapy more efficient
...ross, small enough to enter the nuclear pores. The nanoparticles
consist of a single DNA molecule encased in positively charged peptides and are themselves delivered to cells via liposomes. In cells grown in culture, there was a 6000-fold increase in the expression of a gene packaged this way compared with unpacka...

can penetrate deeper inside human lungs and cause more harm than larger particles because of the inc...
University of New Orleans researcher to head a nine university, three-year, $15.8 million project
...he studies will facilitate the ability to organize nanoparticles
in pre-defined patterns and shapes. This capability will eventually lead to the development of new and improved magnetic, electronic and optical devices," said Dr. Zeev Rosenzweig, UNO associate professor of chemistry, who will in the project. "Thi...
Research paves the way for faster, better, cheaper DNA detection method
...hers at Northwestern University have combined gold nanoparticles
and DNA in a novel way to form tiny probes capable of DNA detection that is more accurate and less expensive than conventional detection methods. The new technology, which uses a flatbed scanner to read the results, could displace polymerase chain ...
