Center for Nano-Optics Becomes Top-Level Georgia State University Research Center
The Center for Nano-Optics has been created at Georgia State University (Atlanta, Georgia), under the leadership of Georgia State Physics Professor Mark Stockman. The center will expand the university?s nanotechnology focus and continue the development of two university inventions ? the spaser, and the nanoplasmonic metal funnel.

The center will expand the university’s nanotechnology focus and continue the development of two university inventions – the spaser, and the nanoplasmonic metal funnel.
The spaser is a laser that is 1,000 times smaller than the smallest laser and also 1,000 times thinner than a human hair. Success in incorporating spaser technology into transistors, something that cannot be done now, may lead to computer processors that operate 100 to 1,000 times faster than today’s processors. Spasers may also help biomedical researchers identify and track single cancer cells in the bloodstream.
The second invention is the plasmonic metal funnel designed with a very thin needle at the end. This technology allows energy to be delivered to very small spaces. The funnel is already widely used in microscopes to give researchers the ability to see on the nanoscale.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
