Abstract
Official abstract text for this publication.
A microchamber electrochemical cell and method of using the cell for performing quantitative analysis of various charged macromolecules is presented. The microchamber electrochemical cell includes a substrate, opposing electrodes and at least one nanoslot. The substrate is configured to define a pair of opposing fluid reservoirs. The pair of opposing electrodes are respectively positioned within the opposing fluid reservoirs. Each nanoslot is configured to fluidly connect the opposing fluid reservoirs together. The opposing fluid reservoirs of the microchamber electrochemical cell are fluidly connected to each other only through each nanoslot. Each nanoslot is physically restricted to less than 500 nanometers. One method includes the steps of coupling, filling, measuring, obtaining, performing and preparing.
