Abstract
Systems and methods are provided for trapping and electrically monitoring molecules in a nanopore sensor. The nanopore sensor comprises a support structure with a first and a second fluidic chamber, at least one nanopore fluidically connected to the two chambers, and a protein shuttle. The protein shuttle comprises an electrically charged protein molecule, such as Avidin. The nanopore can be a Clytosolin A. A method can comprise applying a voltage across the nanopores to draw protein shuttles towards the nanopores. The ionic current through each or all of the nanopores can be concurrently measured. Based on the measured ionic current, blockage events can be detected. Each blockage event indicates a capture of a protein shuttle by at least one nanopore. Each blockage event can be detected through a change of the total ionic current flow or a change in the ionic current flow for a particular nanopore.
