Method for Producing a Device for Electrochemical Detection of Molecules by Means of Redox Cycling, as well as Device Therefor and Its Use

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention presents a new method and device for detecting molecules (such as biomolecules or other analytes) electrochemically using redox-cycling. The device structure features two electrode layers separated by a porous dielectric layer that can be biofunctionalized. Notably, the assembly is produced using printing techniques (like inkjet printing), making bulk fabrication fast, reproducible, and low-cost compared to traditional lithography methods. The device can rapidly and sensitively detect target molecules in solution, with the possibility to include biomolecules (e.g., antibodies, DNA) directly during manufacturing.

Patent Abstract

The invention relates to a method for producing a device for electrochemically detecting molecules by means of redox-cycling, and to a device therefore and use thereof. A porous dielectric layer, which can absorb redoxactive molecules, is arranged between two electrode layers and is eventually biofunctionalised. The individual layers are applied, preferably, by means of a ink jet printing method.
