Patent ID: 8204565

Claim:
An implantable microspectrometer, comprising: an optical sampling cell within a cell housing, said cell housing further defining a fluid inlet port and a fluid outlet port, the fluid inlet port configured to receive an optical sampling fluid from a test subject; an electromagnetic radiation source in communication with a first portion of the optical sampling cell housing and configured to irradiate at least a portion of the optical sampling fluid with electromagnetic radiation; and an electromagnetic radiation detector in communication with a second portion of the optical sampling cell housing and configured to detect electromagnetic radiation emanating from the optical sampling cell, wherein the implantable microspectrometer can optically detect at least one parameter of an analyte contained within the optical sampling fluid in the absence of a reagent, and wherein the implantable microspectrometer occupies a total volume in the range of from about 0.01 cm 3 to about 1.0 cm 3 .
