Spaghetti-like, DNA 'noodle origami' the new shape of things to come for nanotechnology

14 декабря, 2017 - 22:03
Scientists have invented a major new advance in DNA nanotechnology. Dubbed 'single-stranded origami,' their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA, that can self-fold -- without even a single knot -- into the largest, most complex structures to date. The strands forming these structures can be made inside living cells, opening up the potential for nanomedicine.

Nanotexturing creates bacteria-killing spikes on stainless steel surfaces

13 декабря, 2017 - 17:56
By using an electrochemical etching process on a common stainless steel alloy, researchers have created a nanotextured surface that kills bacteria while not harming mammalian cells. If additional research supports early test results, the process might be used to attack microbial contamination on implantable medical devices and on food processing equipment made with the metal.

Improving cyber security in harsh environments

13 декабря, 2017 - 17:53
Many people don't worry about the security of their personal information until it's too late. And protecting data is even more important for military personnel, whose lives could be in danger if some types of information were to get into the wrong hands. Now, one group reports a new way to protect data, especially when it is subjected to extreme environmental conditions.

Visualizing single molecules in whole cells with a new spin

12 декабря, 2017 - 20:54
Scientists have adapted DNA-PAINT technology to microscopes that are widespread among cell biology laboratories, called confocal microscopes, and that are used by researchers to image whole cells and thicker tissues at lower resolution. They have demonstrated that the method can visualize a variety of different molecules, including combinations of different proteins, RNAs and DNA throughout the entire depth of whole cells at super-resolution.
