Abstract
Disclosed is a method for manufacturing an analysis chip for analysing a biological sample (1), which method comprises providing a matrix (10) formed in a solid support material in which at least one through hole has been formed (11) and at least one pellet (3), cut out of a sheet (6) of solid and porous analysis material; inserting at least one pellet (3) into the at least one through hole (11) of the matrix (10) by translation of the pellet (3) in a direction at right angles to the lower and upper surfaces of the matrix (10); mechanically assembling at a temperature lower than the melting points of the support and analysis materials by means of a pressing force applied at right angles to the upper surface of the matrix.

Method for manufacturing a biological sample analysis chip, wherein the method comprises:
- a matrix formed in a solid support material, having a lower surface and an upper surface and in which at least one hole extending between said lower and upper surfaces has been formed, is provided, wherein said through hole is a cylinder of revolution;
- at least one pad is provided, cut from a sheet of solid and porous analysis material, said pad having a lower surface and an upper surface,
- the at least one pad is inserted into the at least one through hole of the matrix by translation of the at least one pad in the direction normal to the lower and upper surfaces of the matrix;
- a mechanical assembly is carried out at a temperature below the melting temperatures of the support and analysis materials, during which a pressing force in the direction normal to the lower and upper surfaces of the matrix is exerted on at least one portion of the matrix which adjoins said at least one pad inserted into the matrix and/or on at least one of the lower and upper surfaces of the at least one pad inserted into the matrix, said mechanical assembly of the at least one pad with the matrix resulting in the at least one pad being crimped on at least a portion of its lower and upper surfaces by the matrix.
Biological sample analysis chip, wherein the biological sample analysis chip comprises:
- a matrix formed in a solid support material, having a lower surface and an upper surface and in which at least one through hole extending between said lower and upper surfaces has been formed, said through hole being a cylinder of revolution;
- at least one pad, cut from a sheet of solid and porous analysis material and inserted into the at least one through hole, the at least one pad having a lower surface and a upper surface,
- and characterized in that the at least one pad is crimped on at least one of its upper and lower surfaces by the matrix.
