This diagram depicts the process of depositing DNA onto a chip containing lines of a polymer that has the opposite charge as DNA, causing the genetic material to be attracted automatically to the polymer. The researchers then stretched the DNA along the lines of polymer, uncoiling the genetic material so that its coded information might be read clearly. Inset images taken with an atomic force microscope show the lines and the DNA molecules. The work was done by Albena Ivanisevic, an Purdue University assistant professor of biomedical engineering, and physics doctoral student Dorjderem Nyamjav. Results are being published in the journal Advanced Materials. (Purdue University Department of Biomedical Engineering/Albena Ivanisevic)
Researchers at Purdue University are making it easier to read life’s genetic blueprint.
They have precisely placed strands of DNA on a silicon chip and then stretched out the strands so that their encoded information might be read more clearly, two steps critical to possibly using DNA for future electronic devices and computers.
Findings about the research are detailed in a paper posted online this month and will appear in an upcoming issue of the journal Advanced Materials. The paper was written by Albena Ivanisevic, an assistant professor of biomedical engineering at Purdue, and physics graduate student Dorjderem Nyamjav.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
