While silicon BioFETs can interact with biology, they perform poorly in air and water. Cardea Insight biosensors combine the best of these two types of transistors, GFET and BioFET, into a proprietary digital technology called Field Effect Biosensing (FEB). With FEB, graphene biosensors are used to measure biomolecular interactions. Graphene is considered a “super material,” with high electrical conductivity and surface area that makes it extremely sensitive to even the smallest of electrical changes. Hence it has an exceptional application in detecting biomolecular interactions which currently depend on less sensitive, non-portable optical techniques such as Surface Plasmon Resonance (SPR), Bio-layer Interferometry (BLI) and Mesoscale Thermophoresis (MST).
