    摘要: Biosensor comprising a flow cell and a detection device having the flow cell coupled thereto, the flow cell and the detection device forming a flow channel that is configured to have biological or chemical substances therein that generate light emissions in response to an excitation light, the detection device including a device base having a sensor array of light sensors and a guide array of light guides, the light guides configured to receive the excitation light and the light emissions from the flow channel, each of the light guides extending into the device base along a central longitudinal axis from an input region of the light guide toward a corresponding light sensor of the sensor array, the light guides including a filter material that is configured to filter the excitation light and permit the light emissions to propagate therethrough toward the corresponding light sensors, the device base including device circuitry that is electrically coupled to the light sensors and configured to transmit data signals based on photons detected by the light sensors; wherein the device base includes peripheral crosstalk shields located therein that at least partially surround corresponding light guides of the guide array, the crosstalk shields at least partially surrounding the corresponding light guides about the respective longitudinal axis to reduce optical crosstalk between adjacent light sensors.
