ABSTRACT:
The present invention is directed toward novel matrix elements, generally comprising functionalized carbon nanotubes, for matrix-assisted laser desorption ionization (MALDI)-mass spectroscopy (MS), methods of making such matrix elements, and to methods of using such matrix elements in MALDI-MS applications, particularly for the analysis of biological molecules. In some embodiments, by carefully tuning the absorption characteristics of the matrix element, biomolecular analytes can be sequenced.
