The Biosensor Company™

At Stemloop, we build custom biosensors, informative tools that allow for unparalleled access to chemical data. Using the power of biology, biosensors inform action at a scale unmatched by traditional methods.

The Biosensor Advantage

How Can a Biosensor Help You?

What if we could detect toxic heavy metals at the faucet, trace pesticides from farm to fork, or measure health and wellness markers in the privacy of our home? Real-time decisions require real-time information. Biosensors make chemical data as accessible as digital data, unlocking informed action for our target industries.
