Don't leave your child's allergies up to chance.

Test their food for peanut – anytime, anywhere​

Know in minutes

Know if your food is really peanut free. Put food into a test capsule, put the capsule in the sensor, and push start. See your result in 2-3 min!


Each test capsule contains peanut-detecting chemistry engineered and proven by MIT scientists. It works on liquids, solids, restaurant foods, and packaged foods.


Test food for peanut at the playground, when traveling, or at home. Fits in your palm, jeans pocket, or purse.

Nima can help

Nima uses antibody based chemistry to test a sample of food for peanut protein. Just place a small amount of food into a new peanut test capsule, insert the capsule into the sensor, push the button, wait a few minutes, and see the result! Since Nima tests a sample of food, not your entire dish, please use Nima’s test result as an additional data point to use alongside all your normal precaution.

Nima can test almost any food, liquid or solid! For example, soups, sauces, ice cream, salads, nut butters, baked goods, cereals, granola, packaged foods, & more.

We designed Nima to be easy enough for anyone in the family to use. In fact, many Nima Peanut Sensor beta testers reported that their children enjoyed using Nima. We do recommend children be supervised by adults in order to establish good testing practices. Nima tests a sample of food — not the entire dish — so all testers, regardless of age, should continue to use all normal precautions when choosing what to ingest.

Our Science - a lab in your pocket

Nima’s antibody-based chemistry was developed by MIT scientists to be faster, cheaper, and usable right at the dinner table. Nima is optimized to detect 10 parts per million of peanut protein and above. 10 ppm is the lowest adverse reaction level observed in patients during clinical research studies.
