Abstract
Translocation events are sensed using composite nanopore assemblies including nanopores formed in graphene sheets. Single molecule detection and characterization and multi-molecule characterization and identification are provided using such assemblies. Multiple electrodes associated with nanofluidic sensors facilitate detection of ionic current through a nanopore as well as tunneling currents. Current signals of individual molecules are estimated from the combination of an ionic current signal through the nanopore and tunneling current signals obtained at specific locations within the nanopore.
