Provided is a method for detecting a target molecule. The method includes providing a chip, the chip including a nanopore in a membrane that is disposed adjacent to or in proximity to a sensing electrode. A nucleic acid molecule is then directed through the nanopore, the nucleic acid molecule being associated with a reporter molecule. The nucleic acid molecule also includes an address region and a probe region, the reporter molecule being associated with the nucleic acid molecule at the probe region. The reporter molecule is also coupled to a target molecule. While the nucleic acid molecule is directed through the nanopore, the address region can be sequenced to determine a nucleic acid sequence of the address region. The target molecule can then be identified, with the aid of a computer processor, based upon the nucleic acid sequence of the address region.
