The innovation lies in modifying conventional sensors by incorporating advanced materials like graphene and its derivatives. These materials, derived from carbon, a widely abundant and renewable element, offer exceptional properties, including high molecular adsorption capacity, excellent electrical conductivity, and outstanding mechanical strength. Their multifunctionality supports material efficiency by significantly reducing the volume of resources required for sensor 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 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.
