Patent ID: 8535905

Claim:
A method for isolating a part of a layer of biological material, comprising the steps of: a) adhering the layer of biological material to one side of a stabilization layer and applying the stabilization layer to a slide with the biological material therebetween, wherein the stabilization layer surrounds the biological material and is adhered along an edge to the slide for protection of the biological material from contamination, b) providing a substrate and applying a bonding layer to at least one side of the substrate, and wherein the material of the bonding layer is a material suitable for promoting adhesion between the stabilization layer and the substrate; c) bringing the side of the substrate with its bonding layer into contact with the stabilization layer on the side of the stabilization layer facing away from the layer of biological material; d) with a focused laser beam describing a closed or substantially closed curve at the layer of biological material to be isolated where it erodes and excises only the biological material and the stabilization layer at the described curve; and e) then separating the substrate to which those excised portions of the stabilization layer and of the biological material adhere by means of the bonding layer.
