Abstract

Embodiments provide silver detection systems and methods for detecting the presence of silver ions in one or more samples. In a detection method, a sample and TPEA2 molecules are introduced into a channel. A first potential difference is applied across the length of the channel in a first direction, and a first electrical property value is detected. Subsequently, a second potential difference is applied across the length of the channel in a second opposite direction, and a second electrical property value is detected. Presence or absence of silver ions in the channel is determined based on a comparison between the first and second electrical property values.
