We are learning to use nanomaterials to build electronic sensors that interface with biology on a range of size scales. Nanometer-sized sensors can monitor single molecule kinetics, and micrometer-sized sensors can study single-cell and collective cellular phenomena. Exciting advances in this field are driven by materials discovery and a deeper understanding of nanoscale processes. I will use examples from my research to illustrate the physics that governs nanoelectronic sensors, including the electronic structure of carbon nanotubes and graphene, the interfacial structure of liquids contacting graphene, and the screening of electric fields by dissolved ions and dielectric liquids. Specific examples include: Carbon-nanotube-based devices that are sensitive to the motion of a single electron charge [1]; graphene-based devices that operate at the thermal noise limit [2]; and flexible graphene-based devices that wrap around a single cell to detect action potentials.
