  • Laser microdissection on inverted polymer films
    Patent number: 7456938
    Abstract: Systems and methods for automated laser microdissection are disclosed. A sample of biological material is located between a polymer membrane and a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the polymer membrane. An infrared laser activates at least a portion of the transfer film such that the transfer film in the vicinity of targeted portion of biological material adheres onto the polymer membrane. The infrared laser is directed in a closed or substantially closed curve around the targeted portions or directly at the targeted portions. The transfer film is then separated removing the targeted portions of biological material which are adhered along with the membrane from the remaining portion of the tissue sample.
