Abstract
A system that incorporates the subject disclosure may include, for example, a method for selectively applying an electrical potential to a top surface of a membrane having a nanopore to repel or attract a molecular strand from the top surface of the membrane, applying a second electrical potential to a bottom surface of the membrane to repel or attract the molecular strand from the bottom surface of the membrane, applying a third electrical potential to an electrolyte solution to apply a transport force on the molecular strand to displace a section of the molecular strand into the nanopore, arresting the section of the molecular strand in the nanopore by adjusting of the first electrical potential, the second electrical potential, the third electrical potential, or combinations thereof, and measuring a signal at the nanopore to identify the section of the molecular strand. Other embodiments are disclosed.
