The project aims at the development of a new electronic nose based on quartz crystal microbalance bio-sensors modified with gold nanoparticles bearing peptides.
Different types of peptides will be tested and the optimal conditions for sinthesys, modification of the surface and sample measurement will be found. The sensor arrays will then be challenged with samples obtained during the production of artisanal beer. An innovative approach for the development of gas sensing systems will be realized. Quartz crystal microbalances surface will be nanostructured using gold nanoparticles funtionalised with peptides.
The project will constitute the first step for the generation of a large library of new gas sensors to be used in many different food chains applications at costs affordable also by SMEs.
