Surface tension acts at the interface between liquids and gases. The time-dependent influence of Surfactants is measured using the dynamic bubble pressure method.
The Fluorescence measurement method uses the property of organic substances to fluoresce. The intensity of the fluorescence is measured in the unit RFU: Relative Fluorescence Unit.
Wettability describes the ability of a surface to be wetted by a liquid. The Contact angle is a measurand of this wettability and indicates the angle formed between the surface and the liquid.
