Device for Measuring Potentials and Method for Manufacturing Such a Device

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

This patent describes a device for measuring electrical potentials in biological, chemical, or other samples, using at least one semiconductor nanowire arranged on a substrate. The nanowire is coated with a dielectric base layer and an additional carbon-containing layer, combining diamond-like and graphite-like carbon, which offers improved stability when used in liquid biological environments. The patent also covers a manufacturing method for producing such devices with this enhanced coating.

Use CasesContent extracted from patent full text and abstract with AI.

• Biosensors for detecting biomolecules in medical diagnostics (e.g., blood, saliva, urine samples)
• Chemical sensors for environmental monitoring of water quality or pollutants
• Lab-on-a-chip devices for real-time sample analysis
• Food safety testing for contaminants or pathogens
