Our research has proven that we are able to immobilize diatoms in a polyvinyl alcohol matrix. The created diatom-PVOH coating was successfully engineered to expose the diatom morphology with microstructures creating a good platform for paper based gas sensor application in food packaging.
This unique formulation shows high sensitivities in the volatile basic nitrogen detection at 63 ppm, representing comparable sensitivity to that reported for nanosensors for nitrogen gas detection.
The benefits for our application include the beneficial morphology for gas sensor, the adaptability in paper material processes, its low cost (USD 1 < per lb.), its safety of use in food applications and its availability for scaled up low cost industrial processes. Therefore, we will continue to work on using in-vitro food samples for the detection of bacteria based volatile basic nitrogen compound emission as looking for other opportunities in immobilization o bioassay enabling antibodies, enzymes and salts to this very attractive nature nanostructured media.
