title: Ion selective optodes: from the bulk to the nanoscale.
abstract: This review describes recent advances in the miniaturization of ion selective optodes into microscale and nanoscale sensors. The topics include a comparison between film-based and miniaturized ion optodes, equilibrium and exhaustive detection modes, recent preparation methodologies and applications of microscale and nanoscale ion optodes, criteria for the design of optode sensors, and other future perspectives.
