Boston, Massachusetts What is the background for this study? What are the main findings?

Response: The incidence of food allergy is increasing worldwide, particularly among children, and yet no handy test is available for general public. We wanted to solve this issue. Our pilot test showed wide variation in allergen contents in packaged food products and restaurant meals. Hidden allergens (like gluten in salad dressing, likely from additives) were also found. What should readers take away from your report?

Response: Most exciting result is that the system can be used for on-site food detection. Our detection kit (dongle) is small and easy to use, and the test is complete within 10 minutes. These capacities can really empower consumers to take control of their food intake. What recommendations do you have for future research as a result of this study?

1) Expanding detection targets. We are already getting many requests to add different allergens.

2) Designing the next generation system that can perform the entire assay in a single integrated device (“sample-in and answer-out”) Thank you for your contribution to the community.
