A software tool for plasmonic biosensors

In many application fields, chemical and biological sensors require a smart device to monitor them, such as laptops with specific software installed. Numerous biochemical sensors are based on small-size plasmonic platforms with high sensitivity. Thus, a system was accomplished to support the potentialities of a novel tool relative to plasmonic sensors in waveguides that can be applied in several biosensor configurations, where the measurements can be carried out in spectral mode. In particular, the sensors based on a surface plasmon resonance (SPR) phenomenon represent a very sensitive method for detecting specific substances, exploiting several kinds of receptors combined with them. The typical configuration of these sensors is arranged to measure the transmitted light spectrum. First, the light is radiated by a halogen lamp, illuminating the SPR sensor, and then it is collected by a spectrometer connected to a Laptop. The proposed measurement system is managed by software titled “Spectra Analysis by Universal Tool” (SAUT). The developed software tool can configure the instrumentation, the network, the database and the folder to save the experimental results.
Thus, the proposed tool could be used in several application fields requiring a user-friendly interface, e.g., point-of-care applications, environment monitoring, Internet of things (IoT) applications, security, and industrial applications.
