Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

This review discusses a relatively new technique for optical nanoimaging at visible
wavelength, known as tip-enhanced Raman spectroscopy (TERS). This technique relies on …

An analytical technique operating at the nanoscale must be flexible regarding variable
experimental conditions while ideally also being highly specific, extremely sensitive, and …

Diffraction of light prevents optical microscopes from having spatial resolution beyond a
value comparable to the wavelength of the probing light. This essentially means that visible …

Raman spectroscopy is a valuable tool in various research fields. The technique yields
structural information from all kind of samples often without the need for extensive sample …

This consistent and systematic review of recent advances in optical antenna theory and
practice brings together leading experts in the fields of electrical engineering, nano-optics …

Surface-enhanced Raman scattering (SERS) was discovered three decades ago and has
gone through a tortuous pathway to develop into a powerful diagnostic technique. Recently …

Surface-and tip-enhanced Raman and LSPR spectroscopies have developed over the past
15 years as unique tools for uncovering the properties of single particles and single …

We report for the first time the tip‐enhancement of resonance Raman scattering using deep
ultraviolet (DUV) excitation wavelength. The tip‐enhancement was successfully …

This paper presents an overview on the principles of tip‐enhanced Raman spectroscopy
(TERS). The technique can be used to record Raman images of carbon nanotubes with high …
