Abstract
The invention provides a substrate for use in an ion source of a mass spectrometer system. The substrate may be employed independently or in conjunction with an ion source or a mass spectrometry system. A substrate is provided having at least one pattern recognition site and a carbon nanotube adjacent to the pattern recognition site. Methods of making and ionizing samples using the pattern recognition site and carbon nanotube surface are also disclosed.
