Rectification occurs when the flow of ions changes depending on the sign" (plus or minus -- positive or negative) of the voltage applied. Using a combination of experiments, simulations, and theoretical modeling, they found that both rectification and gating arise from the nanopore's own electrical charges and the way those charges interact with the ions moving through the pore. How Nanopores Learn Like the Brain The researchers discovered that rectification happens because of how the charges along the inner surface influence ion movement, making it easier for ions to flow in one direction than the other, similar to a one-way valve. Gating, in contrast, occurs when a heavy ion flow disrupts the charge balance and destabilizes the pore's structure."
