Graphene quantum resistive sensing skin for the detection of alteration biomarkers

Sensing skins made of reduced graphene oxide based quantum resistive vapour sensors have been developed by combining two original processes, i.e., the synthesis of phase transferable graphene sheets using ionic liquidpolymers and the structuring of 3D conducting architectures by the spray layer by layer technique

Scholarcy highlights

  • Sensing skins made of reduced graphene oxide based quantum resistive vapour sensors have been developed by combining two original processes, i.e., the synthesis of phase transferable graphene sheets using ionic liquidpolymers and the structuring of 3D conducting architectures by the spray layer by layer technique
  • Many advantages can be derived from this new technology, such as versatility of fabrication, flexibility, potential transparency and low cost, making vQRS skins very attractive to develop the generation e-noses with quick response time, room temperature operability, high sensitivity and adjustable selectivity
  • This can open the door to a wide range of applications, in particular smart packaging, making the monitoring of the quality/safety of food possible by following volatile organic solvents biomarkers emitted during its alteration
  • Comparing pristine RGO, RGO–PIL and RGO–PIL/PEDOT QRS undoubtedly establishes the superiority of the latter in terms of sensitivity and selectivity for the detection of volatile organic solvents released from food during its degradation. The reason for this can be found in the unique architecture of the transducer, optimizing functionalization in solution by the combined action of PIL and PEDOT and structuring in the solid state by the step by step assembly in 3D by spray layer by layer
