Abstract
Various sensors and arrays of sensors that utilize nanostructures or carbon structures, such as nanotubes, nanotube meshes, or graphene sheets, are disclosed. In some arrangements, at least a pair of contacts are electrically coupled with a given nanostructure or carbon structure to sense a change.
Claims20
A system for calorimetric sensing, the system comprising:
- a plurality of calorimetric sensors arranged in an array;
- and
- a processor;
- wherein each of the plurality of calorimetric sensors comprises:
- a first electrical contact;
- a second electrical contact spaced from the first electrical contact;
- a nanotube oriented between the first and second electrical contacts, the nanotube being electrically coupled with each of the first and second electrical contacts;
- a reactor covalently coupled to the first nanotube, the first reactor comprising a molecule configured to chemically interact with a target material;
- and
- a circuit coupled with the first and second electrical contacts;
- and
- wherein the processor is electrically coupled with the circuits of a plurality of the calorimetric sensors, the processor configured to determine whether a reaction at the reactors of a plurality of the calorimetric sensors occurs based on a measured change in voltage across the nanotube.
