An interview with Volker Deckert, the winner of the 2013 Charles Mann Award for Applied Spectroscopy.

The first in the 2013 podcast series presented in collaboration with the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS), in connection with SciX 2013, the federation’s North American conference.

Volker Deckert is a professor at the Institute of Physical Chemistry at Friedrich-Schiller University of Jena and at the Institute of Photonic Technology, both in Jena, Germany.

The goal of his group’s research is to push the lateral resolution of vibrational spectroscopy. The main tool for their projects is tip-enhanced Raman scattering (TERS).

They use plasmonic nanoparticles with specific optical properties at the very end of a sharp tip. With such a probe, lateral resolution well below the Abbe limit can be achieved, and the limits of detection reach single-molecule sensitivity. Because the tip can be moved with sub-nanometer precision, structural information with unmatched spatial resolution can be achieved without the need of specific labels.

About the Charles Mann Award

The Charles Mann Award is presented to an individual who has demonstrated advancements at a conference presented by FACSS in the field of applied Raman spectroscopy and/or demonstrated dedication to the advancement of the Raman spectroscopy program at a conference presented by FACSS or the ASTM Raman subcommittee.

More about the SciX conference:

The traditional North American meeting of FACSS is now SciX — The Great Scientific Exchange. SciX covers the whole of analytical chemistry with an emphasis on emerging technologies. SciX carries on the FACSS tradition of a strong technical program (over 100 symposia), many prestigious awards, exhibits, a variety of workshops, an employment bureau and multiple social networking opportunities.

SciX is the National Meeting of the Society for Applied Spectroscopy (SAS) and the North American Society for Laser-Induced Breakdown Spectroscopy (NASLIBS).
