Abstract
The concept of “Single-molecule spectroscopy” becomes widely known in recent days, particularly aft er the nobel lecture in chemistry in 2014, which is entitled “Single-molecule spectroscopy, imaging, and photocontrol: Foundations for super-resolution microscopy” by the novel laureate W. E. Moerner. Th is talk focused on the development of super-resolved fl uorescence microscopy using fl uorescent tags attached to specifi c molecules. While, as a spectroscopist, one can expect the phrase “single-molecule spectroscopy” to directly obtain the vibrational information from any type of single specifi c molecule by this technique, since we know that the important technical backgrounds for it may already exist as i.e., surface-enhanced Raman scattering (SERS), tip-enhanced Raman scattering (TERS), surface-enhanced coherent anti-stokes Raman scattering (SE-CARS) or surface-enhanced hyper Raman scattering (SEHRS). Th ese plasmon-enhanced vibrational spectroscopies have a certain potential to detect any type of molecules at single-molecule level. However, only few specifi c molecules were reported as target molecules at single-molecule level using SERS, TERS, SE-CARS and SEHRS, therefore, the conceptual steps remains to realize a further achievement on “Single-molecule spectroscopy”. In this meeting, we will discuss perspectives for what will be needed to complete the single-molecule vibrational spectroscopy. Every researchers working on plasmon-enhanced vibrational spectroscopy (SERS, TERS and SE-CARS), vibrational spectroscopy and/or plasmonics are all welcome to the meeting. Nanotechnology for plasmon-enhanced vibrational spectroscopy will also be discussed as an important topic.
