Engineers from Duke University have described progress building so-called "smart nanostructures," including billionths-of-a-meter-scale "nanobrushes" that can selectively and reversibly sprout from surfaces in response to changes in temperature or solvent chemistry.
In talks delivered during the March 28-April 1 at the American Chemical Society annual meeting in Anaheim, researchers from Dukes Pratt School of Engineering also told how they are using an atomic force microscope to create reprogrammable "nanopatterns" of large biologically-based molecules that could potentially serve to analyze the protein contents of individual cells, among other uses.
The molecules are reprogrammable in the sense that they could be activated, deactivated, and then activated again for another use. They could serve as analytical tools because they could capture and isolate proteins of interest from complex mixtures.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
