Monitoring Protein Adsorption with Solid-state Nanopores [PDF]
Journal of Visualized Experiments, 2011 Solid-state nanopores have been used to perform measurements at the single-molecule level to examine the local structure and flexibility of nucleic acids, the unfolding of proteins, and binding affinity of different ligands. By coupling these nanopores to the resistive-pulse technique, such measurements can be done under a wide variety of conditions ...

Slowing DNA Translocation in a Solid-State Nanopore [PDF]
Nano Letters, 2005 Reducing a DNA molecule's translocation speed in a solid-state nanopore is a key step toward rapid single molecule identification. Here we demonstrate that DNA translocation speeds can be reduced by an order of magnitude over previous results. By controlling the electrolyte temperature, salt concentration, viscosity, and the electrical bias voltage ...
