20090252649 | Apparatus for body fluid analysis using surface-textured optical materials - A variety of characteristics of body fluid may be measured by introducing a sample to a textured surface on optical material such as waveguides and sheets. The textured surface presents a field of elongated projections which are spaced apart to exclude certain components of the body fluid sample from entering into the spaces between the projections, while permitting other parts of the body fluid sample which contains the analyte to enter into those spaces. The analyte contacts a chemistry on the surface which is sensitive to the analyte, whereupon the analyte and the analyte-sensitive chemistry interact in a manner that is optically detectable. The optical material is packaged in suitable structures such as elongated cylinders, flat test strips, and sheets. A structure containing the optical material is mounted on a detector, which both illuminates the optical material and detects and analyzes the light that returns from the textured surface. | 10-08-2009 |
