GAS-PHASE PURIFICATION OF BIOMOLECULES BY ION MOBILITY FOR PATTERNING MICROARRAYS AND PROTEIN CRYSTAL GROWTH

摘要

A method and device for the gas-phase separation of ionic biomolecules including peptide, and protein or inorganic cluster ions or nanoparticles by ion mobility and for depositing them intact on a surface in a spatially addressable manner is described. The surface onto which the proteins are deposited can be modified for the purpose of constructing microarrays of biologically relevant materials or for promoting the growth of highly ordered protein crystals.
