The primary objective of the project was to develop innovative porous membranes fabricated from polymer shrink films, designed to function as modern sensors based on polarized liquid interfaces. These advanced materials provide new opportunities in chemical and biological detection, combining high analytical sensitivity with the unique physicochemical properties of the membranes.
The project was of particular significance for food quality control. The designed sensors enable the monitoring of concentrations of selected biogenic amines, antibiotics and alkaloids in food samples, which is crucial for consumer safety. In addition, the developed solutions enable tracking food spoilage mechanisms in products such as milk, which can be used in the food industry and quality control systems.
