Abstract:
A method for identifying an unknown molecule bound to a substrate in a substrate-linking moiety-unknown molecule complex, comprising the steps of:(a) providing a substrate-linking moiety-unknown molecule complex comprising (i) a substrate bound to a plurality of sulfur linking moieties by a plurality of Sâ€”Au bonds and (ii) a plurality of unknown molecules bound to the plurality of linking moieties by a plurality of Sâ€”C bonds; (b) bombarding the complex with focused energized particles selected from the group consisting of Ar and H2 ions to separate at least one of the unknown molecules from the complex; and (c) determining the molecular weight of the at least one of the unknown molecules separated from the complex by time of flight secondary ion mass spectrometry.
