Sentences with phrase «gold nanowires»

By varying the concentrations of AHL and Tc, the scientists can create a biofilm laced by rows of gold nanowires, creating a network that conducts electricity.

The authors of the Angewandte Chemie study, Liangfang Zhang and Joseph Wang from the University of California San Diego, and their colleagues now propose ultrasound - propelled gold nanowires as an active transport / release vehicle for the Cas9 - sgRNA complex over the membrane.

Gold nanowires may cross a membrane passively, but thanks to their rod - or wirelike asymmetric shape, active motion can be triggered by ultrasound.

Tomoya Ono and Kinkuji Hirose at Osaka University in southern Japan performed computer simulations to determine the electromagnetic properties of helical gold nanowires.

The calculations performed by Tomoya and Kinkuji were based on previous experiments and observations of helical gold nanowires.

Gold nanoparticles are attached to threads of gold nanowires.

By programming cells to produce different types of curli fibers under certain conditions, the researchers were able to control the biofilms» properties and create gold nanowires, conducting biofilms, and films studded with quantum dots, or tiny crystals that exhibit quantum mechanical properties.

Each consisted of a plasmonic gold nanowire atop a semiconducting layer of titanium dioxide.

They assembled the vehicle by attaching the Cas - 9 protein / RNA complex to the gold nanowire through sulfide bridges.

«The asymmetric shape of the gold nanowire motor, given by the fabrication process, is essential for the acoustic propulsion,» the authors remarked.

To prevent that, the researchers coated a gold nanowire in a manganese dioxide shell and encased the assembly in a Plexiglas - like gel electrolyte.

Not exact matches

The gold strips act as gates: A voltage applied to them stops or starts the flow of electrons through the main nanowire with an unprecedented combination of speed and precision.

These proteins can be used to precipitate gold from a solution, craft aluminum nanowires to form semiconductors, or soak up dyes or heavy metals from contaminated water, according to researchers.

Viewed under an electron microscope, the gold nanoparticles and nanowires appear fused together like berry clusters on a branch.

An experiment that, by design, was not supposed to turn up anything of note instead produced a «bewildering» surprise, according to the Stanford scientists who made the discovery: a new way of creating gold nanoparticles and nanowires using water droplets.

One group at Lund University in Sweden has been able to kick - start the spontaneous growth of «forests» of 1000 - nm - high «nanowire trees», using 50 - nm - wide clusters of gold as a catalyst, and a gallium phosphide substrate.
