Self-assembly of super-hydrophobic PMMA microspheres on silicon wafer as MALDI-MS chip for rapid quantification of peptides

•A novel super-hydrophobic structured-PMMA chip for MALDI-MS is prepared by a simple self-assembly method.•The MALDI-MS detection reproducibility and sensitivity are highly improved with this chip compared to the conventional steel target.•Different peptides can be quantified in a broad range with t...
