摘要： Layered implantable sensors are described herein. Layered sensors described herein may include one or more analyte sensing populations. The one or more analyte sensing populations may detect different analytes, or different concentrations of the same analyte, for example. The layered sensors may include a reference population. The reference population may, or may not, be analyte sensing. As described herein, the first sensing population may be separated from a second sensing population (and/or a reference population) by a passive layer.

摘要： 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.
