First Claim
Patent Images
1. 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.

Abstract
Dry laminated photoluminescent probe (10) and methods of manufacture and use. The probe (10) includes a support layer (30) with a plurality of separate and independent optically active particles (20) dry laminated onto a first major surface (30a) of the support layer (30) forming a sensing area (15) on the support layer (30). The optically active particles (20) are preferably laminated onto the support layer (30) via a layer of pressure sensitive adhesive (40).
