Abstract:
1. A method for laser microdissection comprising the steps of: providing a first substrate having an upper surface; providing a membrane having an upper surface and a lower surface; providing a layer of biological material; locating the layer of biological material between the lower surface of the membrane and the upper surface of the first substrate; providing a second substrate having a surface with a transfer film adhered thereto; the transfer film having adhesive characteristics upon activation by electromagnetic energy; identifying at least one targeted portion of biological material to be microdissected; placing the second substrate with the transfer film into juxtaposition with the first substrate on the upper side of the membrane in the location of the at least one targeted portion of biological material such that the transfer film is between the second substrate and the membrane; providing a laser source; activating the laser source to emit a laser beam; directing the laser beam so as to activate at least a portion of the transfer film and fuse the portion of the transfer film to the membrane; and separating the second substrate with its attached transfer film, a portion of the membrane fused to the transfer film and the at least one targeted portion of biological material adhered to the membrane from the remaining layers of membrane and biological material.
