A system and method for automated transfer of a tape segment onto the face of a tissue block to be thin sectioned by microtomy includes applying, to a carrier strip, a plurality of serially-spaced patches of sample tape having an adhesive outer surface, transporting the carrier strip along a path adjacent to and spaced from the exposed sample surface to position one of the patches of sample tape adjacent to and covering the exposed sample surface, adhering the one of the patches of sample tape to the exposed sample surface.

Disclosed is plate or film for collecting and analyzing a sample. The plate or film includes a surface and a plurality of slices from the sample immobilized on the surface. Further, the plurality of slices are cut from the sample with equal thickness, and the plurality of slices are placed on the surface of the plate or film following their cutting order.

A method for preparing dyeing sample. The method for preparing dyeing sample includes (a) passing a biological sample containing a object to be stained through an non-epoxy-based microfilm to collect the object to be stained on the non-epoxy-based microfilm; (b) immobilizing the object to be stained on the non-epoxy-based microfilm with a fixing agent at a fixation time; and (c) staining the object to be stained on the non-epoxy-based microfilm by using at least one filtered dye.

Provided herein are methods of preserving a biological sample on a first substrate, the methods including: (a) disposing a biological sample on a first substrate; (b) delivering a spacer agent to the first substrate, wherein the spacer agent is applied around the biological sample on the first substrate, thereby generating a chamber around the biological sample; (c) delivering a mounting agent to the chamber; and (d) assembling the first substrate with a second substrate, thereby preserving the biological sample on the first substrate.
