A surface modification method is presented: a sodium chloride crystal, a transparent wide bandgap insulator, was deposited onto a stainless steel surface. The surface was subjected to various stimuli to induce surface defects either on the steel surface or salt crystal and the ion yield of substance P, a model peptide, was investigated as a function of stimuli. The interaction of the laser at potential defect sites resulted in an increase in the ion yield of substance P (3–17 fold increase relative to no stimuli).
