Super small nanoelectrodes can probe microscale environments

Posted on 11. Mar, 2007 by admin.

Investigating the composition and behavior of microscale environments, including those within living cells, could become easier and more precise with nanoelectrodes being developed at the University of Illinois.
“The individual nanotube-based probes can be used for electrochemical and biochemical sensing,” said Min-Feng Yu, a U. of I. professor of mechanical science and engineering, and a researcher [...]

Gold nanorods assemble themselves into rings

Posted on 11. Mar, 2007 by admin.

Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures.
This finding, which will be published as the inside cover article of the March 19 international edition of the chemistry journal Angewandte Chemie, could potentially lead to the development of novel nanodevices like highly sensitive optical sensors, [...]
