Abstract:
Substrates, methods for making the substrates and methods for using the substrates for mass spectrometry analysis are provided. Methods include coating a conductive substrate having a hydrophilic surface (suitable for mass spectrometric analysis) with an uncharged hydrophobic surface, masking a subset of regions on the hydrophobic surface with an insulator, and applying an oxidizing force to the unmasked regions of the hydrophobic surface to render the unmasked regions hydrophilic.
