摘要： Disclosed herein are a method and device for determining a property of an ambient environment. The device comprises a plasmonic sensing element (100); a first light source (130) for illuminating a first and a second light sensor (110, 120), the first sensor (110) via the plasmonic sensing element (100); a second light source (140) for illuminating the light sensors (110, 120); circuitry for executing: a control function (152) controlling light sources (130, 140), a function (154) receiving a measurement from the first sensor (110), and a first signal from the second sensor (120), a function (156) receiving a reference from the first sensor (110), and a second signal from the second sensor (120), a function (158) determining the property by comparing the measurement and reference signals, and the control function (152) further controlling light sources (130, 140) such that a relation of intensities of light emitted by the light sources (130, 140) is constant over time.

摘要： The present invention relates to a sensor for detecting an analyte in a fluid. The sensor (200) comprising: a fluidic channel (102) arranged to receive a flow of the fluid, a plasmonic sensor (202) which upon resonant excitation exhibits a localized surface plasmon resonance condition thereby forming a sensing volume (206) within the fluidic channel (102), wherein the plasmonic sensor (202) is partly arranged within the fluidic channel (102), a binding portion (208) arranged inside the sensing volume (206) for binding the analyte. A system for detecting an analyte in a fluid, the system comprising the sensor, and a method for detecting an analyte in a fluid are also presented.
