Femtomolar detection of Cu2+ ions in solution using super-Nernstian FET-sensor with a lipid monolayer as top-gate dielectric

[Display omitted] •A new Di-picolylamine-lipid sensitive layer for the detection of Cu2+ in solution.•Lowest limit of detection (10 fM) reported for small ions in solution.•First FET sensor using a lipid monolayer as ultra-thin top-gate dielectric showing a super-nernstian behavior.•Very high stabil...
