TERS gives the vibrational information of a sample with nanometric resolution. Obtaining physico-chemical information with such resolution opens up possibilities to characterize materials at unprecedented levels which allows research findings unsuspected until recently.

This webinar introduces the fundamentals of TERS through the history of near-field spectroscopic optics. From the great idea of Synge over 90 years ago to the technical progress of scanning probe microscopy, the history of near-field optics crosses the emerging plasmonics field and the discovery of the amplification of the Raman signal by Van Duyne.

This webinar will also briefly present the current applications of this nanospectroscopic technique in 2D materials and other semiconductors, but also for biological samples such as viruses, cells, and DNA.
