Abstract
A method for selectively depositing analysis-enhancing fluid on a sample surface is disclosed. The method involves providing a sample having a surface that exhibits variations in a surface characteristic that corresponds to desirability for receiving an analysis-enhancing fluid. Once a site on the sample surface is selected according to the surface characteristic at the site, focused radiation, typically acoustic radiation, is applied in a manner effective to eject a droplet of the analysis-enhancing fluid from a reservoir. As a result, the droplet is deposited on the sample surface at the selected site. Optionally, the sample at the selected site is analyzed. Systems for selectively depositing analysis-enhancing fluids are also disclosed.
