Argonne nanoscientist Elena Rozhkova is studying ways to enlist nanoparticles to treat brain cancer. This nano-bio technology may eventually provide an alternative form of therapy that targets only cancer cells and does not affect normal living tissue.

Nanoscientists at Argonne are working on a technique to attack brain cancer cells using these coin-shaped magnetic disks. Antibodies on the surface of the disks latch onto cancerous cells. Then, when a weak magnetic field is applied, the disks begin to oscillate, killing the cancer cells. The disks are just a single micron across – about 10 times smaller than the diameter of a single red blood cell. Though the technique is still in early stages of testing, it shows promise.

The Journal of Nanomedicine and Nanotechnology under Open Access category depicts the scientific and technological advances in the field of medical, biological and nanoscale sciences. The Journal includes the online, peer-reviewed research speculating the latest developments in the growing fields of medical and nanoscale technologies, owing to bring tremendous changes in medicine.

Researchers from Sunchon National University in Suncheon, South Korea, and Rice University in Houston have built a radio frequency identification tag that can be printed directly onto cereal boxes and potato chip bags. The tag uses ink laced with carbon nanotubes to print electronics on paper or plastic that could instantly transmit information about a cart full of groceries

Artwork of molecular model of a DNA nucleosome, the repeating unit used to package DNA (genetic material) inside the nucleus of cells. The spiral helix of DNA (red, blue) is seen coiled around a core of histone proteins (centre, multicolored) and each set of two DNA loops around a histone core is known as a nucleosome.
