System and Method for Detection of Silver

摘要

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.

1. A method for detecting the presence or absence of silver ions in a sample, the method comprising:
introducing a sample into a channel, the channel having a length and a width, the length substantially greater than the width; measuring an electrical property value of an electrical property along at least a portion of the length of the channel after the sample is introduced into the channel; accessing a reference electrical property value, the reference electrical property value associated with the electrical property of the channel along at least a portion of the length of the channel prior to introduction of the sample into the channel; comparing the measured electrical property value and the reference electrical property value; and determining whether silver ions are present in the channel based on the comparison between the measured electrical property value and the reference electrical property value.
