In asymmetric warfare, early detection and identification of trace level chemical and biological agents and explosive compounds is critical to rapid reaction, response, and survivability.
Duke University bioengineers have not only figured out a way to sneak molecular spies through the walls of individual cells, they can now slip them into the command center -- or nucleus -- of those cells, where they can report back important information or drop off payloads.
While pondering the challenges of distinguishing one nano-sized probe image from another in a mass of hundreds or thousands of nanoprobes, researchers at Georgia Tech and Emory University made an interesting observation. The tiny, clustered dots of light looked a lot like a starry sky on a clear night.
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
