  • Abstract:
    A controller for surface plasmon resonance biosensor has been designed and applied for analysis of aqueous substances. A core provides the necessary signals for control and sensor actuation. Using a 16 bits A/D converter to convert the analog signals generated by the sensor and polynomial algorithm, the sensor output noise are reduced around 37.5%. The digital data are sent to computer for processed and displayed. Details regarding the physics construction of the controller and its programming, including system validation tests presented in this paper.
