摘要： The present invention generally discloses the use of a nanostructured non-silicon thin film (such as an alumina or aluminum thin film) on a supporting substrate which is subsequently coated with an active layer of a material such as silicon or tungsten. The base, underlying non-silicon material generates enhanced surface area while the active layer assists in incorporating and transferring energy to one or more analytes adsorbed on the active layer when irradiated with a laser during laser desorption of the analyte(s). The present invention provides substrate surfaces that can be produced by relatively straightforward and inexpensive manufacturing processes and which can be used for a variety of applications such as mass spectrometry, hydrophobic or hydrophilic coatings, medical device applications, electronics, catalysis, protection, data storage, optics, and sensors.
