The invention provides a method for analyzing a material, comprising:n providing a vesicle suitable for carrying a fluid having said material therein, disposing said vesicle adjacent a first location of a surface of a substrate, controlling said vesicle to deliver a nanoliter volume of the fluid to provide a defined and controlled volume of said fluid at said first location of said surface of the substrate, moving said vesicle to a second position adjacent a second location on said surface of the substrate to dispense a defined and controlled volume of said material along an array of locations on said substrate surface, and performing mass spectrometry analysis for said material at each location of said array. |
