Abstract
This invention provides a mass spectrometry probe including a substrate having a surface and a film that coats the surface. The film includes openings that define features for the presentation of an analyte. The film also has a lower surface tension that the surface tension of the substrate surface, and has a water contact angle between 120° and 180°.
