Solid-state nanopores (SSNs) are single-molecule resolution sensors with a growing footprint in real-time bio-polymer profiling-most prominently, but far from exclusively, DNA sequencing. SSNs accessibility has increased with the advent of controlled dielectric breakdown (CDB), but severe fundamental challenges remain: drifts

In this study, we investigated the voltage and pH responsiveness of human serum transferrin (hSTf) protein using silicon nitride (Si xN y) nanopores. The Fe(III)-rich holo form of hSTf was dominant when pH > pI, while the Fe(III)-free apo form
