    摘要: Systems and methods are disclosed for evaluating the length of elongated elements in a sample. The disclosed systems and methods may include using a direct current stimulus to determine a direct current base length region corresponding to at least a portion of the sample. Furthermore, the disclosed systems and methods may include using an alternating current stimulus to determine that the direct current base length region corresponds to a first set of elongated elements and a second set of elongated elements. The first set of elongated elements may have a first base length and the second set of elongated elements may have a second base length. The elongated elements may comprise, for example, chain molecules, deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or proteins. Furthermore, the disclosed systems and methods may include measuring an ion current through a nanopore, the ion current produced by the alternating current stimulus.
