Abstract: Device having a flat macroporous support material made of silicon and having surfaces, a plurality of pores each having a diameter in a range of from 500 nm to 100 ?m distributed over at least one surface region of the support material and extending from one surface through to the opposite surface of the support material, at least one region having one or more pores with SiO2 pore walls, and a frame of walls with a silicon core surrounding the at least one region and arranged essentially parallel to longitudinal axes of the pores and open towards the surfaces, wherein the silicon core merges into silicon dioxide over a cross section towards an outer side of the walls forming the frame.

Abstract: Device having a two-dimensionally formed support material which has, spread across at least one surface area, a plurality of pores which stretch throughout from one surface of the support material to the opposite surface, wherein the pores are bound in each case by a pore boundary area of pore walls formed in the support material along particular longitudinal axes of the pores, and at least part of the pore walls have at least in some sections a layered structure containing a first layer forming the pore boundary area and a second layer adjacent to the first layer and spaced apart from the pore boundary area, and wherein the refractive index nwaveguide of the first layer is greater than the refractive index n2 of the second layer.

Abstract: An apparatus, in which at least one pipette in the form of a through-hole with a predetermined diameter is formed in a substrate, with a rim of the through-hole projecting by a predetermined amount from an adjacent surface of the substrate.

Abstract: A method for detecting a biochemical reaction includes immobilizing a capture molecule on an inner wall of a pore selected from a multiplicity of pores extending between first and second opposed surfaces of a macroporous substrate and contacting an analyte with the capture molecule. A light is then directed into the pore. A change in a light transmission property of the pore is then detected. This change indicates a binding reaction between the analyte and the capture molecule.
