The innovation in this study lies in enhancing conventional sensors through the integration of advanced materials such as graphene and its derivatives. These materials, derived from carbon, a widely abundant, renewable, and sustainable element, exhibit exceptional properties, including high molecular adsorption capacity, superior electrical conductivity, and remarkable mechanical strength. Their multifunctionality not only enhances sensor performance but also promotes material efficiency by significantly reducing the resources required for production.
The manufacturing process employs screen printing, a technique that minimizes waste generation and energy consumption compared to traditional methods, contributing to cleaner, more efficient production. This approach promotes the creation of environmentally responsible and accessible analytical devices, advancing diagnostic and real time environmental monitoring technologies while adhering to the principles of waste reduction, resource efficiency, and sustainability.
To validate the performance of these sustainable sensors, a comparison will be conducted with the gold-standard detection method, Liquid Chromatography coupled with Mass Spectrometry (LC-MS), using the same analyte. This evaluation ensures the reliability of the sensors while highlighting their advantages as a greener alternative to conventional techniques that require significant reagent consumption, high energy input, and complex instrumentation.
