In Brief

A small device can detect even small amounts of common food allergens

The iEAT is a new, keychain sized device created by researchers at Harvard Medical School that lets you test food for common allergies. Users can add a small sample of food onto a single-use slide (the antigen extraction device), then snap it on the iEAT device itself, which will then analyze the prepared food sample. The device will show how much allergens are present within ten minutes and even smaller amounts of allergens than lab tests. It’s currently set up to detect common allergens like peanuts, hazelnuts, wheat, milk and eggs, but it could be configured to find less common ingredients and even pesticides.
