The present invention provides methods and systems for selectively eluting
biological material from a distinct spatial location on a microarray
slide. In one aspect, for example, a method for recovering biological
material coupled to a microarray slide can include selecting a biological
material to be recovered from the microarray slide, finding the
biological material within a distinct spatial region on the microarray
slide surface, and eluting at least a portion of the selected biological
material from the distinct spatial region without eluting substantial
amounts of non-selected biological material from regions of the
microarray slide that are not within the distinct spatial region.
