NANOSCALE SENSORS

摘要

A nanocoaxial sensor includes an outer conductor, an inner conductor, a d ielectric material disposed between the outer and inner conductors, a nanoca vity 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 sens ing element is adapted to selectively capture the at least one of the target species.
