Abstract
A library that comprises nanoclusters is prepared by generating nanocluster ions, mass selecting a predetermined monodisperse subset of these nanocluster ions, and depositing a plurality of them in cavities of a substrate. Members of the library may include monodisperse nanoclusters and other materials. After deposition, cavity walls may be removed.

A method for preparing a library of samples that include monodisperse nanoclusters on a substrate, comprising:
- (a) generating gas phase nanocluster ions, each gas phase nanocluster ion comprising from about 3 to about 3000 atoms;
- (b) mass selecting a predetermined monodisperse subset of these gas phase nanocluster ions;
- (c) depositing a plurality of the monodisperse mass-selected nanocluster ions on a predetermined region of a substrate, wherein the predetermined areas comprise substrate cavities, each cavity defined by cavity side walls and a cavity floor, thereby generating a sample of deposited, monodisperse nanoclusters in substrate cavities;
- and
- (d) repeating step (b) and then step (c) for at least another monodisperse subset of nanocluster ions at a different predetermined region on the substrate, thereby generating a library of a plurality of samples of monodisperse nanoclusters on the substrate.
