Patent ID: 6867038

Claim:
A method of direct extraction of cellular material from a tissue sample which comprises: providing a tissue sample; providing a slide for mounting of the tissue sample having a first adhesive attraction to the tissue sample; mounting the tissue sample to the slide; providing a transfer surface which only upon activation at selected regions has a property to provide the selected regions thereof with adhesive characteristics with a second and greater adhesive attraction to the tissue sample; juxtaposing the tissue sample with the transfer surface; identifying at least one portion of the tissue sample which is to be extracted; activating a region on the transfer surface with radiation so that the selected region of the transfer surface adheres to the at least one portion of the tissue sample while preserving focal tissue morphology; separating the transfer surface from the tissue sample while maintaining adhesion between the selected region of the transfer surface and the at least one portion of the tissue sample so that the at least one portion of the tissue sample is extracted from a remaining portion of the tissue sample.
