The development of diagnostic and therapeutic nanoparticles for biomedical applications is
of broad current interest in science, engineering, and medicine. The fundamental basis is …

Changes in protein expression levels and protein structure may indicate genomic mutations
and may be related to some diseases. Therefore, the precise quantification and …

We demonstrate both the observation of either a single or a few molecules resolved within
the inhomogeneous broadening of a peak in surface-enhanced raman scattering (SERS) …

A review is given on single-molecule surface-and tip-enhanced Raman spectroscopy (SERS
and TERS). It sketches the historical development along different routes toward huge near …

Hot spots are highly localized regions of intense local field enhancement believed to be
caused by local surface plasmon resonances (LSPR). Formed within the interstitial crevices …

We report measurements of excitation and emission spectra of single, polymer-embedded,
perylene dye molecules at room temperature. From these measurements, we can derive the …

Spectro-microscopy, a combination of fluorescence microscopy with spatially resolved
spectroscopic techniques, provides new and exciting tools for functional cell biology in living …

In this study we use a combination of absorption, fluorescence and low temperature single-
molecule spectroscopy to elucidate the spectral properties, heterogeneities and dynamics of …

Single-molecule study of phenylenevinylene oligomers revealed distinct spectral forms due
to different conjugation lengths which are determined by torsional defects. Large spectral …

Single-molecule spectroscopy at cryogenic temperatures was used to examine the impact of
buffer solution, glycerol/buffer mixtures (25% and 66%), and poly (vinyl alcohol)(PVA) films …
