Dry laminated photoluminescent probe and method of manufacture and use

A remotely interrogatable optochemical probe which produces a specific measurable optical response to a target analyte from which target analyte can be reliably quantified, the probe comprising:

• (a) a support layer having a first major surface,
• (b) a first layer of pressure sensitive adhesive coated onto the first major surface of the support layer, and
• (c) a plurality of separate and independent optically active particles sensitive to a target analyte, dry laminated and pattern deposited onto the first major surface of the support layer via the first layer of pressure sensitive adhesive coated onto the first major surface of the support layer, so as the form at least one discrete sensing area on the first major surface of the support layer with areas of pressure sensitive adhesive still exposed.
