Droplet based microfluidics: spectroscopic characterization of Levofloxacin and its SERS detection
Levofloxacin (Levo), a second generation fluoroquinolone, has both clinical and environmental relevance. Therefore, the implementation of fast, robust and cost effective techniques for its monitoring is...
PublicationsRaman-Mikrospektroskopie für eine schnelle Erregerdiagnostik
Viele Applikationsfelder in der Lebensmittelindustrie erfordern eine schnelle und zuverlässige Identifizierung pathogener Keime. Die Raman-Spektroskopie als sensitive und hochspezifische Nachweismethode...
PublicationsAqueous Black Colloids of Reticular Nanostructured Gold
Since ancient times, noble gold has continuously contributed to several aspects of life from medicine to electronics. It perpetually reveals its new features. We report the finding of a unique form of...
PublicationsPalladium versus Platin – Das Metall im Katalysezentrum eines molekularen Photokatalysators bestimmt den Mechanismus der Wasserstoffproduktion mit sichtbarem Licht
To develop highly efficient molecular photocatalysts for visible light-driven hydrogen production, a thorough understanding of the photophysical and chemical processes in the photocatalyst is of vital...
PublicationsHole injection dynamics from two structurally related Ru–bipyridine complexes into NiOx is determined by the substitution pattern of the ligands
The dyes bis[2,2'-bipyridine][4,4'-dicarboxy-2,2'-bipyridine]ruthenium(II) dihexafluorophosphate, [Ru(bpy)2dcb](PF6)2 (Ru1) and tris(4,4'-bis(ethylcarboxy)-2,2'-bipyridine)ruthenium(II) dihexafluorophosphate,...
PublicationsPlasmon-driven dimerization via S-S chemical bond in an aqueous environment
The surface-enhanced Raman scattering (SERS) spectra of thioanisole are experimentally investigated in an electrochemical environment in this study. Two Raman peaks, which depend strongly not only on electric...
PublicationsNear field plasmonic gradient effects on high vacuum tip-enhanced Raman spectroscopy
Near field gradient effects in high vacuum tip-enhanced Raman spectroscopy (HV-TERS) are a recent developing ultra-sensitive optical and spectral analysis technology on the nanoscale, based on the plasmons...
PublicationsTime-Resolved Photoluminescence Spectroscopy of Exciton–Plasmon Coupling Dynamics
In this review, we provide a brief overview of the recent progress achieved on the plasmon-enhanced fluorescence technique for the study of exciton–plasmon interactions using time-resolved photoluminescence...
PublicationsPlasmon-driven selective reductions revealed by tip-enhanced Raman spectroscopy
We successfully realized in-situ monitoring plasmon-driven selective reduction of 2,4-dinitrobenzenethiol to 2,2′-diamino-dimercaptoazobenzene, revealed by high vacuum tip-enhanced Raman spectroscopy...
PublicationsTracking heavy water (D2O) incorporation for identifying and sorting active microbial cells
Microbial communities are essential to the function of virtually all ecosystems and eukaryotes, including humans. However, it is still a major challenge to identify microbial cells active under natural...
