Journal ArticleDOI
Nanoscale chemical analysis by tip-enhanced Raman spectroscopy
TL;DR: In this article, a fine metal tip brought to within a few nanometers of a molecular film was found to give strong enhancement of Raman scattered light from the sample, which can be used for molecular analysis with excellent spatial resolution.
Journal ArticleDOI
Identification of polymers as major components of atmospheric organic aerosols.
Markus Kalberer,D. Paulsen,Mirjam Sax,Martin Steinbacher,Josef Dommen,André S. H. Prévôt,R. Fisseha,Ernest Weingartner,Vladimir Frankevich,Renato Zenobi,Urs Baltensperger +10 more
TL;DR: Results from photooxidation of aromatic compounds in a reaction chamber show that a substantial fraction of the organic aerosol mass is composed of polymers, which results in a lower volatility of this secondaryorganic aerosol and a higher aerosol yield than a model using vapor pressures of individual organic species would predict.
Journal ArticleDOI
Ion formation in MALDI mass spectrometry
TL;DR: The origin of ions in matrix-assisted laser desorption/ionization (MALDI) mass spectrometry is currently a matter of active research as discussed by the authors, and a number of chemical and physical pathways have been suggested for MALDI ion formation.
Journal ArticleDOI
Scanning near-field optical microscopy with aperture probes: Fundamentals and applications
Bert Hecht,Beate Sick,Urs P. Wild,Volker Deckert,Renato Zenobi,Olivier J. F. Martin,Dieter W. Pohl +6 more
TL;DR: In this paper, the authors describe the fundamentals of scanning near-field optical microscopy with aperture probes, including instrumentation and probe fabrication, aspects of light propagation in metal-coated, tapered optical fibers, and field distributions in the vicinity of subwavelength apertures.
Journal ArticleDOI
Single-Cell Metabolomics: Analytical and Biological Perspectives
TL;DR: The fact that single-cell measurements exhibited a much larger spread in metabolite concentrations than population measurements was exploited to determine many metabolite-metabolite correlations, which were altered in 2DG-treated yeast cells relative to controls.
