摘要:
The invention relates to a device, especially for patch-clamping vesicles and/or for dispensing small, defined liquid amounts onto surfaces. The device is characterized in that in a substrate (2) at least one pipette in the form of a through hole (8) with a predetermined diameter is produced, a rim (16) of the through hole (8) protruding from a neighboring surface (4) of the substrate (2) by a predetermined length. The invention further relates to a method for producing the device, comprising the following steps: producing at least one hole (8), forming at least one modified surface layer (12) on at least the inner surfaces of the hole (8), selectively removing the substrate (2), the modified surface layer (12) not being substantially affected so that it protrudes from a surface (4) of the substrate and forms a protruding rim (16), and finishing the hole (8) as a through hole in a suitable process step.
摘要:
The invention relates to a device comprising a planar macroporous support material based on silicon, which has a plurality of pores with a diameter ranging from 500 nm to 100 µm, distributed over at least one surface region, said pores extending in a continuous manner from one surface to the opposite surface of the support material. Said device comprises at least one region containing one or several pores with pore walls consisting of Si02, said region being surrounded by a frame that is arranged substantially parallel to the longitudinal axes of the pores, is open in the direction of the surface of the support material and consists of walls with a silicon core. The silicon core changes to silicon dioxide over the cross-section towards the exterior face of the walls that form the frame. The invention also relates to a method for producing said device. The inventive device is suitable for use as a base for a biochip base module in methods for detecting biochemical (bonding) reactions, in addition to analysing for this purpose enzymatic reactions, nucleic acid hybridizations, protein-protein interactions and other bonding reactions in the domain of genome, proteome or active substance research in the fields of biology and medicine.

The invention relates to a device comprising a planar support material (16), which has a plurality of pores (10) distributed over at least one surface region, said pores extending in a continuous manner from one surface (12) of the support material (16) to the opposite surface (14). The invention is characterised in that the pores (10) are delimited along their longitudinal axis by a pore limiting surface (18) of the pore walls (22) configured in the support material (16), that at least one part of the pore walls (22) has, at least in sections, a layered construction comprising a first layer (20) that forms the pore limiting surface (18) and a second layer (24) that is adjacent to the first layer (20) and located at a distance from the pore limiting surface (18) and that the refractive index nWaveguide of the first layer (20) is greater than the refractive index n2 of the second layer (24).
