Development of sensors for mycotoxins

Unsafe levels of toxins in food and feed requires new technology for the detection of these compounds along the food continuum from production to consumption. While traditional analytical techniques exist, there is still a real need for simpler, more rapid, and cost-effective approaches to food safety testing. Biosensors consist of a specific molecular recognition probe targeting an analyte of interest and a means of converting that recognition event into a measurable signal. As molecular recognition is the foundation of biosensing, there has been increased focus on the development of new molecular recognition probes for food-safety monitoring . Because of their in vitro selection and production, the relatively new technology of aptamers is emerging as a viable alternative for use in biosensor platforms. This proposal examines the development of aptamers for food safety related targets with a view to developing biosensor platforms in which these probes can be
