Abstract

The invention relates to a method for producing micro- and / or nanopore mass arrangements on a substrate, comprising the following steps: functionalizing the substrate surface in selected areas by applying a bonding agent; depositing, from an aqueous dispersion on the substrate surface, colloid particles which are capable of selectively binding to the functionalized areas of the substrate surface, an ordered monolayer of the particles forming on the substrate surface; removing non-bound colloid particles; freezing the substrate; and sublimating the residual water on the substrate in vacuo, the short-range order of the particle monolayer remaining intact.

Description

technical field

[0001] The present invention relates to a new method for producing large-area arrays of micropore and nanopore clusters by pure self-organization. The array of holes can be controlled on the surface of the substrate in discrete areas. The size of the holes and the transverse hole spacing can be adjusted in the range of microns and nanometers. Background technique

[0002] Micropores and nanopores or pore arrays, respectively, have numerous applications, eg as biomimetic model systems for simulating and explaining processes occurring at the level of the cell membrane. Nanopore systems are used to regulate intracellular and intercellular transport of ions and molecules and the maintenance of electrical potentials between cells and their environment. Thus, for example, the nucleus of a eukaryotic life form is separated from the rest of the cell by a nuclear membrane with permeable pores. The intertransmission of RNA, proteins and molecules between the nucleus...
