Abstract
A method of using a device to detect a target entity in an environment includes introducing the device into the environment. The device includes first and second conductive surfaces, with a first molecular wire electrically coupling the first conductive surface to a capture agent that can interact with the target entity, and a second molecular wire electrically coupling the second conductive surface to a reference compound. The first and the second molecular wires comprise oligonucleotide multiplexes having identical nucleobase sequences and opposite absolute configuration. The method also includes detecting, by the device, an interaction between the capture agent and the target entity, at least in part by amplifying a differential voltage between the first and second conductive surfaces and detecting the interaction based on the differential voltage.
