CONVEX GEOMETRY ADHESIVE FILM SYSTEM FOR LASER CAPTURE MICRODISSECTION

摘要

A tissue sample is conventionally visualized in a microscope. A selectively activated convex surface is provided, preferably at the distal end of a rod. This selectively activated convex surface when activated, typically with a laser through an optic light path in the microscope, provides the activated region with adhesive properties. At least one portion of the tissue sample which is to be extracted is identified. This identified portion is contacted with a portion of the selectively activated convex surface on the end of the rod. When the convex surface is activated, typically by exposure to laser light in the footprint of the desired sample, an adhesive transfer surface on the selectively activated convex surface is provided which adheres to the desired cells in the footprint of the desired sample. Thereafter, the adhesive transfer surface is separated from the remainder of the tissue sample while maintaining adhesion with the desired cells.
