Abstract:



Batches of water-soluble gold nanoclusters of nominal 2.0 or 3.5 nm diameter were prepared to evaluate particle size determinations by a number of techniques such as transmission electron microscopy or atomic force microscopy and to validate estimates derived by mass spectrometric analysis using matrix-assisted laser desorption ionization (MALDI). Good agreement was found and MALDI lends itself to analyses even in the presence of aggregates.

Keywords: aggregates; measurements; particle size; scanning electron microscopy; scanning probe microscopy; transmission electron microscopy
