摘要

method for the deposition of systems supramolecolari of bio molecules and, in general, molecules of large and / or complex and / or others.comprising mainly the combination of the following: - evaporation, or other mechanisms for desorption and ionization, induced by at least one short pulse laser radiation.of these molecules; molecules ionized in a driving electric field; and the storage of ionized molecules on the support is desired.figure 1 shows an example of the preservation of the integrity of the molecules deposited.figure 1a represents the mass spectrum of the deposited material.stemming from a sample of triptofil - leucine belonging to a surface of a stainless steel, and figure 1b shows the mass spectrum of the same material.deposited after the irradiation and the application of the electric field, analyzed by a new vaporization and ionization induced by laser.
