Mesoporous molecular sieves particles of SBA-15-type with medium and high pore sizes were succesfully applied for the first time in the enrichment and identification of trace peptides and proteins. The direct MALDI-TOF MS analysis protocol eliminates the peptide-elution step and therefore circumvents the risk of sample loss.
