Abstract

The non-uniform deposition of matrix-analyte cocrystals and poor ionization are major obstacles in quantitative analysis through MALDI-MS. An Au-nanobowl array was prepared and applied to overcome these limitations, which enabled the quantitative detection of oligonucleotides and polypeptides.
