Abstract

A characteristic difference between first and second liquids is measured using a surface having a monolayer of a voltage sensitive chromophore that is covalently bound to the surface. The first liquid is brought into contact with the surface and it is irradiated with actinic radiation to measure a first fluorescence emission spectrum. The second liquid is also brought into contact with the surface and it is irradiated with actinic radiation to measure a second fluorescence emission spectrum. The first and second fluorescence emission spectra are compared to characterize a difference between the first and second fluids.
