Abstract
This paper presents the conception, design, implementation,
and validation of an original, fully functional biosensor
based on surface plasmon tesonance (SPR) technology.We present
the motivation for building this sensor followed by the system
specification, a brief overview of the theory of operation for SPR
physics, and then give a detailed description of the hardware
design, software design, and immunoassay design. We present a
novel, graphical approach for tracking shifts in SPR center frequency
with an autocorrelation feature that minimizes component
variation. Additionally, we present the wireless communications
aspects of our design, which adds to its appeal for remote system
deployment and autonomous operation. Our success demonstrates
the immediate availability of all the hardware, software, and
biological components required to construct a fully functional
biosensor with industrial application.
