Extremely low concentrations of peptides and proteins can be enriched from complex solutions by SnO2@PMMA and TiO2@PMMA core–shell nanobeads with controlled size and composition (see picture for schematic synthesis), and their MALDI‐TOF MS signal intensities and signal‐to‐noise ratios are also significantly improved. These effects are ascribed to the physical properties and structure of the nanobeads. PMMA=poly(methyl methacrylate).
A facile approach is demonstrated for the preparation of mesoporous carbon nanowires in nanotubes, mesoporous carbon nanotubes and mesoporous carbon nanothorn microspheres by combining surfactant-templating self-assembly of organic resols with different MnO(2) hard templates, and they deliver excellent capacitive performance for supercapacitor applications.
Extrem niedrige Konzentrationen an Peptiden und Proteinen können aus komplexen Lösungen mithilfe von SnO2@PMMA‐ und TiO2@PMMA‐Kern‐Schale‐Nanokügelchen definierter Größe und Zusammensetzung (Synthese siehe Schema) angereichert werden, und man erhält deutlich bessere Signalintensitäten und Signal‐Rausch‐Verhältnisse in MALDI‐TOF‐Massenspektren. Die Effekte werden mit den physikalischen Eigenschaften und der Struktur der Nanokügelchen erklärt. PMMA=Poly(methylmethacrylat).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
