Embodiment Construction

[0035] In the following description, reference is made to the accompanying drawings which form a part hereof and which illustrate several embodiments of the invention. It is understood that other embodiments may be utilized and structural and operational changes may be made without departing from the scope of the present invention.

[0036] As shown in the drawings for illustrative purposes, embodiments of the present invention relate to optical sensors that can be verified by an optical system or an optoelectronic system. Optical sensors may be introduced and / or contained percutaneously, or may be implanted in and / or through subcutaneous, dermis, sub-dermis, interperitoneal or peritoneal tissue. In the discussion herein, preferred embodiments of the devices, systems and methods of the present invention are described with reference to glucose as the analyte, the level / concentration of which is to be determined in the user's blood and / or bodily fluids. This is however by way o...

Abstract

An optical glucose sensor may include an optical fiber and a glucose-permeable membrane having a hollow interior and being coupled to the optical fiber's distal end. The membrane's hollow interior provides a compartment to house a competitive glucose binding affinity assay. The assay may include a glucose analog that may be labeled with a dye, and a glucose receptor that may be labeled with a fluorophore. The optical fiber may include a compound parabolic concentrator tip, and the compartment may additionally house a reflector disposed so as to face the optical fiber's tip. A fluorophore-labeled assay may be interrogated by an optical interrogating system including a light source and a filter substrate having one or more coatings to effect, e.g., an excitation filter and / or an emission filter. The interrogating system may be manufactured as a stacked planar integrated optical system and diced into smaller units.
