Abstract: Some embodiments described herein relate to a sensor that includes a first a first polymer-luminescent sensing compound configured to produce a first luminescent signal in the presence of a first analyte and a second polymer-luminescent sensing compound configured to produce a second luminescent signal in the presence of a second analyte. The second luminescent signal can have a luminescent lifetime that is at least 1.1 times greater than a luminescent lifetime of the first luminescent signal. Such temporally differences in signal can be used to deconvolute the first luminescent signal from the second luminescent signal even when, for example, the first luminescent signal and the second luminescent signal have the same or a similar emission spectrum.

Abstract: Some embodiments described herein relate to an apparatus including a light source configured to transmit an excitation optical signal to an implanted sensor and a detector configured to detect an analyte-dependent optical signal emitted from an implanted sensor. The apparatus can include a lens configured to focus at least a portion of the analyte-dependent optical signal onto the detector.

Abstract: An optical device is used to monitor an implant embedded in the tissue of a mammal (e.g., under the skin). The implant receives excitation light from the optical device and emits light that is detected by the optical device, including an analyte-dependent optical signal. Scatter and absorption properties of tissue change over time due to changes in hydration, blood perfusion and oxygenation. The optical device has an arrangement of light sources, filters and detectors to transmit excitation light within excitation wavelength ranges and to measure emitted light within detection wavelengths. Changes in scattering and absorption of light in the tissue, such as diffuse reflectance, are monitored. The light sources, filters and detectors may also be used to monitor autofluorescence in the tissue to correct autofluorescence background.

Abstract: The invention provides methods for directing a localized biological response of a mammalian body to an implant disposed within the body. In one embodiment, a delivery system is positioned outside the body and adjacent to the implant within the body. The delivery system comprises a first tissue response modifier effective for directing a localized biological response of the body to the implant. The tissue response modifier is nonsurgically delivered from the delivery system into the body in a quantity effective to direct the localized biological response of the body to the implant. The invention also provides an implant system for long-term use comprising an implant and nonsurgical means for delivering a tissue response modifier through the epidermis of the body, the tissue response modifier effective for directing a localized biological response of the body to the implant.
