A biosensing device for continuous monitoring of an analyte in a fluid matrix includes an electromagnetic excitation element [], a biosensing surface [], an opposing surface [], a separation component [], light collection optics [], a light sensor [], an image recording and analysis system [], and an excitation control system []. The separation component is connected to the biosensing surface and to the opposing surface, forming a concave gap region [] between the biosensing surface and the opposing surface. The biosensing surface comprises biosensing particles sensitive to electromagnetic signals from the electromagnetic excitation element, where an optical response of the biosensing particles to the electromagnetic signals is adapted to change in the presence of an analyte in the gap region. The light collection optics couple light emitted from the biosensing particles on the biosensing surface to the light sensor. The image recording and analysis system is connected to the light sensor and processes light signals from the biosensing particles to determine presence or absence or concentration of the analyte in the fluid matrix.
