Abstract: Embodiments profile cannabinoids using a nanopore detector. Embodiments use an applied potential to electrophoretically draw a nanopore blockade reporter molecule into a nanopore channel to establish an electrophoretic molecular channel-capture for the reporter molecule. The reporter molecule includes one of an aptamer or a monoclonal antibody and has a specific binding to at least one of: a specific cannabinoid, a particular cannabinoid isoform; or a specific cannabinoid family. Embodiments receive a blockade channel current signal in response to a nanoscale membrane channel of the nanopore detector being partially blockaded by a presence of the reporter molecule non-covalently bonded to the membrane channel. Embodiments receive a blockade signal for the reporter molecule that is toggling between more than one level.
