ACS Nanotation

[Nano Letters] We present an investigation of the morphology and composition of novel types of axial nanowire heterostructures where Ga_x_In_1-x_As is used as barrier material in InAs nanowires....

...The impact of increased amounts of silver in the environment is subject to study and debate; among the concerns are that silver may kill beneficial bacteria and other small organisms....

Socks and other garments that stay odor-free thanks to antimicrobial nanoscale silver particles are increasingly showing up on store shelves. But what happens to the silver when such products are washed remains an open question...

... The ability to form metal–molecule–metal (MMM) junctions has been one of the primary goals of researchers working in the field of ‘molecular electronics’ because these junctions allow for the fundamental measurement of charge transport through molecules....

In the spirit of the season, we report on a new study from the Journal of Agricultural and Food Chemistry that describes the antimicrobial properties of pumpkin skins....suggesting that it could be developed into an anti-fungal therapy.

Managing Editor Penelope Lewis and Sarah Tegen highlight features and research content from Volume 3, issue 10. In this episode, we learn about using nanomaterials for global and homeland security. Featuring an interview with author Michael Natan.

In the first ChemMatters video, we find about why the very smallest machines, known as nanotechnology, hold very big promise.

A scanning electron micrograph of ZnO nanorods on a SnO2 nanowire backbone. The density and morphology of the ZnO branches can be tailored by changing the reaction conditions... [Cover by Cheng et al., pg. 3069, DOI:10.1021/nn900848x]

Here, we show that DsrA, a 87-nt noncoding RNA of Escherishia coli, self-assembles into a hierarchy of nanostructures through antisense interactions of three contiguous self-complementary regions.

We'll celebrate National Chemistry Week with a quiz and a chance for you to win a copy of Theodore Gray's new book, The Elements. Mr. Gray is a self-described "element nut."

A musical extravaganza on the importance and execution of laboratory safety. Visit us at http://www.TheSoundsOfScience.com and check out our other videos, including The Nano Song

The Sounds of Science is a small group of graduate students and recent alumni of UC Berkeley that share a common love of science and music. Our aim is to promote awareness of science to the community of all ages through fun music videos available free on the internet.

We report pronounced and specific antiglioblastoma cell phototoxicity of 5 nm TiO2 particles covalently tethered to an antibody via a dihydroxybenzene bivalent linker....The phototoxicity is mediated by reactive oxygen species (ROS) that initiate programmed death of the cancer cell.
