Hybrid nanowires show promise as nanotechnology building blocks

A very brief but intriguing article on ScienceDaily reports that millimeter-scale nanotech structures self-assembled from hybrid nanowires can sense and respond to external stimuli, like magnetic fields and light. From “Building Giant ‘Nanoassemblies’ That Sense Their Environment“:

Researchers in Texas are reporting the design, construction, and assembly of nano-size building blocks into the first giant structures that can sense and respond to changes in environmental conditions.

The study, scheduled for the July 9 issue of ACS’s Nano Letters [abstract]… terms those structures “giant” because they are about the size of a grain of rice — millions of times larger than anything in the submicroscopic realm of the nanoworld.

In the new study, Pulickel M. Ajayan and colleagues point out that such structures are a step toward the development of futuristic nanomachines with practical applications in delivering medicines to patients, labs-on-a-chip, and other products. Until now, scientists have had difficulty in using nanomaterials to build more complex, multifunctional objects needed for those applications.

    This is very fascinating stuff! So how can this be used to bootstrap more controllable atomically-precise nanomachine structures?
