Patent: Tip Enhanced Laser Assisted Sample Transfer for Biomolecule Mass Spectrometry

Link

Disclosed are various embodiments for transferring molecules from a surface for mass spectrometry and other sample analysis methods, and the like. A laser is focused onto a tip of an atomic force microscope to remove and capture a quantity of molecules from the surface, so they can be transferred to a mass spectrometer or another instrument for analysis.
