Graphene is the scaffolding which we dope and add other materials to make each element (think scent receptor, e.g. in your nose) on our sensor array unique. If you imagine each element on the 10-element array chip – each element is its own unique sensor that attracts or repels specific gases. Similar to how your nose receptors work, certain gases only bond to specific receptors on our chip. Those reactions create our digital signatures (digital fingerprints), which are added to our Scent Studio.
