Abstract: The present disclosure concerns methods, systems, and devices for analyzing a biological material, such as a cellular or other specimen. In one disclosed example, the method selectively transfers biomolecules from a target region of interest in a biological sample (such as a tissue section). The transfer may occur, for example, by selectively focally altering a characteristic of a transfer layer adjacent the target region, such that the biomolecules can move through the altered area of the transfer layer. In particular examples, the transfer layer is altered by focally increasing a permeability of the transfer layer, for example by removing a focal portion of the transfer layer, and transporting the biomolecules through the altered region of the transfer layer, to microdissect the biomolecules of interest from the biological sample.
