TryNano.org is a resource for anyone interested in learning about Nanoscience and Nanotechnology. Nanoscience and Nanotechnology are technical fields that focus on matter at the nanoscale - dimensions that are roughly 1 to 100 nanometers (1nm = 10-9m).

The term Nanoscience often refers to research that discovers and characterizes new behaviors and properties of materials at the nanoscale. Nanotechnology describes how discoveries at the nanoscale are put to work, especially by controlling the behavior of matter and building useful devices. Some of these devices have demonstrated applications in medicine, electronics, robotics, and energy production.

The next generation of nanosubmarines being developed at Rice University has been upgraded with tags that fluoresce longer, which enables the submersibles to be tracked for greater periods while being driven through a solution. The single-molecule vehicles introduced by the Rice lab of chemist James Tour last year may someday be used to deliver drugs or other cargo. The new version was built and tested with collaborators at Tel Aviv University in Israel. The first nanosub, USN-1, could be monitored but not imaged by a technique that would irradiate it with light for very short times. But that did not offer information about the submersible’s trajectory, according to lead author Víctor García-Lopéz, a former Rice...
