Superheroic Imaging Sensitivity

Posted February 09, 2010 7:52 AM

Increased sensitivity is always better for imaging instruments, and Raman spectroscopists just reported a vibrational IR instrument sensitive to zeptomolar concentrations of some materials. The paper in PNAS reports a nanoplasmonic technique adaptable to any commercial microscope, boosting signal levels to 100,000x for absorption spectroscopy.

The preceding article is a "sneak peek" from Scientific Instruments, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Scientific Instruments today.

Thank you for this! The article is available free for a limited time when it's new, otherwise I would have to go dig in a library.

This is a great example of how nanotech stands to enhance imaging and change our view of the world from <shrug> "we speculate" to <nod> "we know".
