Raman Spectroscopy of Graphene-Based Materials
Raman spectroscopy is a versatile tool to identify and characterize the chemical and physical properties of graphene-based materials. It provides information on graphene structures for fundamental research and for practical device fabrication. Raman scattering demonstrates the first- and second-order modes in intrinsic graphene as well as the shear, layer-breathing, and the G and 2D modes of multilayer graphene. Professor Ping-Heng Tan from the State Key Laboratory of Superlattices and Microstructures at the Institute of Semiconductors at the Chinese Academy of Sciences is carrying out new research to advance the use of Raman analysis of these materials. We recently interviewed Tan about this work.

The Rise of Raman Spectroscopy in Biomedicine
In recent years, more and more academic research has been conducted on the use of Raman spectroscopy for biomedical applications. Effectively moving the technique from the research laboratory to the clinic, however, requires overcoming a number of challenges, ranging from dealing with fluorescence interference to automating the process enough to make it easy for medical staff to implement. Juergen Popp and his team at the Leibniz Institute of Photonic Technology and the Friedrich-Schiller University, in Jena, Germany, have been working to address these challenges, with the aim of making Raman spectroscopy a powerful, comprehensive tool for cell biology and clinical studies. He recently spoke to Spectroscopy about this work.
