Summary: Viruses are major pathogens in food poisoning, and the development of foodborne virus detection technologies for the entire food distribution chain is crucial for food safety. Polymerase chain reaction (PCR) is the gold standard method for monitoring food contamination by viruses, but it is time-consuming and vulnerable to inhibitors in food samples. Optical and electrical readout biosensors based on nucleic acid isothermal amplification technology and nanomaterials have emerged as alternatives, offering portability and on-site operation. However, the complexity of food components and lack of stability studies on residual food components limit the practical application of biosensors as a universal detection method.

Summary: There is an urgent need to improve a specific, equipment-free and user friendly technique for detecting melamine in food samples. Melamine imprinted polymeric membranes were synthesized and tested for selectivity. The membranes showed 7.575 times more sensitivity for melamine than the competitor agent cyromazine. A new kind of smart polymer, named lab-on-polsystem, was successfully applied for on-site colorimetric analysis.
