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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
