Abstract

A method of detecting a target substance includes providing a number of molecular tethers at a channel surface of a sensor such that at least some of a plurality of beads, as a result of a biological interaction between a target substance and the tethers, are attached to the channel surface by the tethers or released from the channel's surface by cleaving the tethers. This method further includes introducing an analyte into the channel and determining the population of beads at the channel surface to indicate a presence of the target substance in the analyte.
