Gold nanoparticle capping layers: structure, dynamics, and surface enhancement measured using 2D-IR spectroscopy


Donaldson, Paul M; Hamm, Peter (2013). Gold nanoparticle capping layers: structure, dynamics, and surface enhancement measured using 2D-IR spectroscopy. Angewandte Chemie Internationale Edition, 52(2):634-638.

Abstract

Surface analysis: Two-dimensional infrared spectroscopy (2D-IR) was used to probe amide and carboxylate functional groups in the vicinity of gold nanoparticles and their aggregates. The data presented shows that the unique ability of 2D-IR spectroscopy to characterize broadening mechanisms and cross peaks offers new insights into gold nanoparticle capping layer structure and dynamics (see picture).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
