Directed evolution builds nanoparticles

ScienceDaily.com: Nanotechnology News - Wed, 02/27/2019 - 20:11
Directed evolution is a powerful technique for engineering proteins. Scientists now show that it can also be used to engineer synthetic nanoparticles as optical biosensors, which are used widely in biology, drug development, and even medical diagnostics such as real-time monitoring of glucose.

Now you see heat, now you don't

ScienceDaily.com: Nanotechnology News - Wed, 02/27/2019 - 20:11
Hiding an object from heat-sensing cameras could be useful for military and technology applications as well as for research. Efforts to develop such a method have been underway for decades with varying degrees of success. Now, researchers report that they have fabricated an inexpensive, easy-to-produce film that makes objects completely invisible to infrared detectors.

A new spin in nano-electronics

ScienceDaily.com: Nanotechnology News - Mon, 02/25/2019 - 20:22
In recent years, electronic data processing has been evolving in one direction only: the industry has downsized its components to the nanometer range. But this process is now reaching its physical limits. Researchers are therefore exploring spin waves -- a promising alternative for transporting information in more compact microchips. Cooperating with international partners, they have successfully generated and controlled extremely short-wavelength spin waves. The physicists achieved this feat by harnessing a natural magnetic phenomenon.
