The Future of Raman Spectroscopy: The Role of TERS and SERS
Attend any conference covering vibrational spectroscopy, and you will likely hear numerous talks about developments in tip enhanced Raman scattering (TERS) and surface-enhanced Raman scattering (SERS). Both approaches hold exciting promise, but face significant challenges as well. We asked a panel of Raman experts about the current and future role of these two approaches. |

FT-IR for Cancer Diagnosis
Matthew Baker of the University of Strathclyde in Glasgow, Scotland, has been using infrared spectroscopy for the analysis of biological samples. The noninvasive procedure allows for the rapid detection of diseases and provides an opportunity for early administration of a therapeutic strategy, when the treatment is most effective. Spectroscopy spoke with him about his work in this area using attenuated total reflection (ATR) and ATR combined with Fourier transform infrared (FT-IR) spectroscopy. |

Raman Spectroscopy and Imaging of Low-Energy Phonons
External vibrational modes or low-energy phonons are very sensitive to crystal structure. Here, the author demonstrates the practicality of imaging low-energy phonons to characterize 2D crystals and provides some cautions to keep in mind. |
