IMPROVED MASS SPECTROMETRIC ANALYSIS USING NANOPARTICLES

摘要

The invention relates to an improved method for mass spectrometric analysis, especially for matrix-assisted laser desorption/ionisation time-of-flight ma ss spectrometry (MALDI-TOF-MS), using nanoparticles. An analyte is added to a nanoparticle suspension and the suspension containing the bound analyte is then deposited directly on a MALDI sample carrier and is analysed by mass spectrometry. The invention also relates to nanoparticles which are suitable for said method.
