Beschreibung
Zusammenfassung:	The document describes a sensor, apparatus and method for the direct analysis of fluids in order to determine concentration of solutes in solutions. Transductors with porous birefringent monolayer or multilayer structures (such as a planar photonic structure in the form of a Bragg microcavity) may be used as sensors. The method of the invention can be performed in two possible implementations; a first one, wherein the sensor is a photonic crystal in a microfluidic device which comprises two transparent windows, data being retrieved in transmission mode and a second one, wherein the photonic crystal sensor is located on the tip of an optical fiber, data being retrieved in reflection mode.
