1. A method of applying a paraffin-embedded biological specimen to an analytic substrate, comprising:
using an automatic coating apparatus to apply a coating composition to at least a portion of at least one of an upper surface and a lower surface of an analytic substrate to form a coated analytic substrate having a coated surface thereon, wherein the coating composition comprises an organofunctional silane; and
applying a paraffin-embedded biological specimen to the coated surface of the coated analytic substrate in a histologic floatation water bath in a way that a hydrolytic area is produced between the paraffin-embedded biological specimen and the analytic substrate wherein in situ hydrolysis of the coating composition is initiated by water from the histologic floatation water bath to produce an alcohol thereby causing a flattening of the paraffin-embedded biological specimen upon the coated analytic substrate by removal of water trapped underneath the paraffin-embedded biological specimen and to cause the paraffin-embedded biological specimen to bind to the analytic substrate.
2. The method of claim 1 wherein, when the paraffin-embedded biological specimen is placed on the coated analytic substrate, the organofunctional silane in the coating composition becomes bound by in situ hydrolysis and condensation of at least one reactive silyl group thereof to the analytic substrate, and wherein the paraffin-embedded biological specimen binds to at least one functional group of the organofunctional silane whereby the paraffin-embedded biological specimen becomes bound to the analytic substrate.
3. The method of claim 2 wherein the in situ hydrolysis and condensation does not occur until that time when the paraffin-embedded biological specimen is applied to the coated surface.
4. The method of claim 1 comprising an additional step of applying a quantity of a second coating composition upon the coated analytic substrate after the paraffin-embedded biological specimen has been bound thereto, thereby forming an overcoat upon the paraffin-embedded biological specimen for preserving the paraffin-embedded biological specimen on the coated analytic substrate.
5. A method of applying a paraffin-embedded biological specimen to an analytic substrate, comprising:
using an automatic coating apparatus to apply a coating composition to at least a portion of at least one of an upper surface and a lower surface of an analytic substrate to form a coated analytic substrate having a coated surface thereon, wherein the coating composition comprises organofunctional silane; and
applying a paraffin-embedded biological specimen to the coated surface of the coated analytic substrate in a histologic floatation water bath in a way that a hydrolytic area is produced between the paraffin-embedded biological specimen and the analytic substrate wherein in situ hydrolysis of the coating composition is initiated by water from the histologic floatation water bath to cause the paraffin-embedded biological specimen to bind to the analytic substrate.
6. The method of claim 5 wherein when the paraffin-embedded biological specimen is placed upon the coated surface, an alcohol is produced by the situ hydrolysis of the coating composition resulting in increased adhesion of the paraffin-embedded biological specimen to the coated surface.
7. The method of claim 5 wherein in the step of applying a paraffin-embedded biological specimen, an alcohol is produced by in situ hydrolysis of the coating composition during binding of the paraffin-embedded biological specimen to the coated analytic substrate thereby causing a flattening of the paraffin-embedded biological specimen upon the coated analytic substrate by removal of water trapped underneath the paraffin-embedded biological specimen thereby decreasing the drying time necessary before further processing.
8. The method of claim 5 wherein in the step of applying a paraffin-embedded biological specimen, an alcohol is produced by in situ hydrolysis of the coating composition during binding of the paraffin-embedded biological specimen to the coated analytic substrate thereby causing a flattening of the paraffin-embedded biological specimen upon the coated analytic substrate by removal of water trapped underneath the paraffin-embedded biological specimen.
9. The method of claim 5 wherein, when the paraffin-embedded biological specimen is placed on the coated analytic substrate, the organofunctional silane in the coating composition becomes bound by in situ hydrolysis and condensation of at least one reactive silyl group thereof to the analytic substrate, and wherein the paraffin-embedded biological specimen binds to at least one functional group of the organofunctional silane whereby the paraffin-embedded biological specimen becomes bound to the analytic substrate.
10. The method of claim 5 wherein the in situ hydrolysis and condensation does not occur until that time when the paraffin-embedded biological specimen is applied to the coated surface.
11. The method of claim 5 comprising an additional step of applying a quantity of a second coating composition upon the coated analytic substrate after the paraffin-embedded biological specimen has been bound thereto, thereby forming an overcoat upon the paraffin-embedded biological specimen for preserving the paraffin-embedded biological specimen on the coated analytic substrate.
