Abstract

A sensing method includes exposing a nano-transducer having a controlled surface to a sample including at least one species. Adsorption of the species on the nano-transducer is transduced to a measurable signal as a function of time. Desorption of the species from the nano-transducer is also transduced to a measurable signal as a function of time. A residence time of the at least one species adsorbed on the nano-transducer is extracted from the measurable signals. The adsorption and desorption each define an individual measurable event.
