Abstract:
A method of direct extraction of targeted material from a tissue sample which comprises:providing a tissue sample;providing a convex surface exceeding the size of the targeted material from the tissue sample:adhering a selectively activatable layer to the convex surface to provide a selectively activatable convex surface, the selectively activatable convex surface having the property of being locally activated at a part of the selectively activatable layer to provide an adhesive transfer surface;identifying at least one portion of the tissue sample as the targeted material which is to be extracted;juxtaposing the targeted material of the tissue sample with the selectively activatable convex surface;selectively activating a portion of the selectively activatable convex surface to form the adhesive transfer surface;contacting the tissue sample at the targeted material with the adhesive transfer surface; andseparating the adhesive transfer surface from the tissue sample while maintaining adhesion with the targeted material 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 and attached to the adhesive transfer surface reorienting the convex surface with respect to the tissue sample; andrepeating the identifying, juxtaposing, selectively activating, contacting, and separating to separate additional targeted material on different regions of the selectively activatable convex surface.
