Optical-based sensing devices |
| abstract |
An optical-based sensor (10) for detecting the presence or amount of an analyte using both indicator and reference channels. The sensor has a sensor body (12) with a source of radiation embedded therein (18). A matrix layer is disposed on the surface of the sensor body which layer is permeable to an analyte and comprises fluroescent indicator molecules responsive to the concentration of the analyte. Radiation emitted by the source interacts with indicator membrane (3) indicator molecules (16) proximate the surface of the body. At least one optical characteristic of these indicator molecules varies with analyte concentration. For example, the level of fluorescence of fluorescent indicator molecules or the amount of light absorbed by light-absorbing indicator molecules can vary as a function of analyte concentration. In addition, radiation emitted by the source also interacts with reference membrane indicator molecules proximate the surface of the body. Radiation (e,g., light) emitted or reflected by these indicator molecules enters and is internally reflected in the sensor body. Photosensitive elements within the sensor body generate both indicator channel and reference channel signals to provide an accurate indication of the concentration of the analyte. |
