Globalization and ecological pressures have increased the emergence of novel infections and global pandemics in farmed animals and food industries. This means that not only are livestock at growing risk of contracting new and difficult-to-control diseases, but the people who care for them as well. The world has entered a “4th revolution” in agriculture. This era features novel technologies and diagnostic methods, such as Internet of Things and Precision Livestock Farming. In this talk, I will provide examples of the sensor platforms, the sensing mechanisms and the communication devices developed at the Bionanolab of the University of Guelph. To name some, detection of sex hormone progesterone in milk using ELISA technique; Time resolved fluorescence resonance energy transfer based nanomaterials for detecting metabolic biomarkers from blood, serum and milk samples of dairy cows; in-situ synthesis of gold nanoparticles for rapid and multiplexed detection of food-borne and avian influenza viruses; and quantum dot based sensing of food allergens such as peanut, lupine, okadaic acid detection will be presented. The new frontier in biosensing that we develop in the advanced diagnostic technology development will be a breakthrough not only for on-farm diagnostic translation, but also on various product designs that may be of significance to biosecurity. The biosensing tools has the potential to collect, integrate, report, analyze, share and disseminate valuable information to livestock owners, farmers, producers and health inspection agency members and government veterinary services and inspection agencies by leveraging mobile technology (including Point-of-care (POC) testing, tele-diagnostics, and remote collection devices).
