Nanoscale sensors

摘要

A nanocoaxial sensor includes an outer conductor, an inner conductor, a dielectric material disposed between the outer and inner conductors, a nanocavity sized to allow target species to enter the nanocavity between the outer and inner conductors, and an active sensing element immobilized within the nanocavity on at least one of the inner or outer conductors. The active sensing element is adapted to selectively capture the at least one of the target species.

1. An apparatus comprising:
a first nanocoaxial sensor, comprising: an outer conductor having a first longitudinal axis; an inner conductor having a second longitudinal axis coaxial with the first longitudinal axis; a nanocavity, defined by an inner surface of the outer conductor and an outer surface of the inner conductor, sized to allow target species to enter the nanocavity between the outer and inner conductors; and an active sensing element immobilized within the nanocavity on at least one of the inner or outer conductors, wherein the active sensing element is adapted to selectively capture at least one of the target species.
