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 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 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.
Improving Fluorescence and Raman Techniques for Environmental Microplastic Analysis
March 31st 2025A recent study conducted at the LaserLaB Amsterdam and Vrije Universiteit Amsterdam (the Netherlands) explored spectroscopic imaging techniques, including Raman and fluorescence microscopy, for characterizing microplastics (MPs), focusing on optimizing sample preparation, particularly density separation, and Nile Red staining.Spectroscopy spoke to Merel Konings, corresponding author of the paper resulting from the study, about her work
New Study Provides Insights into Chiral Smectic Phases
March 31st 2025Researchers from the Institute of Nuclear Physics Polish Academy of Sciences have unveiled new insights into the molecular arrangement of the 7HH6 compound’s smectic phases using X-ray diffraction (XRD) and infrared (IR) spectroscopy.
