A sensor for the detection of an analyte, comprising a holographic element comprising a medium and a hologram disposed throughout the volume of the medium, wherein an optical characteristic of the hologram changes as a result of a variation of a physical property occurring throughout the volume of the medium, wherein the medium is obtainable by formation in situ in the presence of a pore-forming agent, wherein the agent is not present in the sensor or does not react with the analyte and the sensor.

Method for forming a volume holographic sensor in a porous medium

A sensor which comprises a support medium and a hologram disposed therein, wherein an optical characteristic of the medium varies as a result of a change of a property of the medium, and wherein the medium is heterogeneous such that the change of property is heterogeneous.

Holographic sensor having heterogeneous properties

A sensing method, which comprises subjecting a holographic sensor to an external physical interaction to which the sensor is sensitive, and observing a change in the holographic image.

Sensing method including interrogation of a holographic sensor

An array of discrete sensors disposed on a substrate, each sensor comprising a holographic support medium and a hologram disposed throughout the volume of the medium, whereby interaction with an analyte results in a variation of a property of the medium.

Holographic sensors and their production

A method for the detection of an analyte in a fluid, comprising contacting the fluid with a holographic element comprising a medium and a hologram disposed throughout the volume of the medium, wherein an optical characteristic of the element changes as a result of a variation of a physical property occurring throughout the volume of the medium, wherein the variation arises as a result of interaction between the medium and the analyte, and wherein the reaction and the variation are reversible; and detecting any change of the optical characteristic.
